If the driver is unloaded when D3 debug data pulling is enabled
but not triggered, it doesn't release the data buffer.
Fix this by adding iwl_fw_runtime_free and calling it from the
relevant places.

When the NIC is disconnected, we just can't do anything
besides seeking for help from the bus driver. Dumping the
device's memory is not necessary and just bloats the logs
with unusable data. Moreover, asking mac80211 to restart
the hardware is also useless. Bypass all this.
Also, use the STATUS_TRANS_DEAD status bit instead of a
bool inside the transport layer. The advantage of this is
that now, the transport and the op_mode can know what is the
situation and bypass the useless recovery steps mentioned
above.

A new FW API has been added for WOWLAN_GET_STATUSES to support
multiple GTK keys and IGTK keys. Check the respective TLV and use the
new API when it is set.
Let most of the code use the new version (v7) and convert the old
version (v6) to the new one when needed.
Also refactor some functions a bit so that they can be reused more
easily. Particularly the part that calls WOWLAN_GET_STATUSES which is
reused in D3 and D0i3.

Trying to collect firmware debug data while firmware
is not loaded causes various errors (e.g. failing NIC access).
This causes even a bigger issue if at that time the
HW radio is off.
In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
bit is cleared on faulty NIC access - since the same behavior
was seen in HW RFKILL toggling before setting that bit.)

If FW loads without a problem, leaving init_dbg on can
cause a confusion, since the user won't necessarily
remember it is still turned on, and there are flows in
which everything continues as usual, only without
stopping the device after INIT, even if there is no FW
assert. On 22000 HW, for instance, this causes a
warning, since the paging is getting initialized twice.
Solve the issue by making this module param effective
only if the FW indeed asserts during INIT.

We need to have a station and a queue for the monitor

Allocate a new queue, link it to the monitor vif's station
and make that queue use the BE fifo.

to READ_ONCE()/WRITE_ONCE()
Please do not apply this to mainline directly, instead please re-run the
coccinelle script shown below and apply its output.
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't harmful, and changing them results in
churn.
However, for some features, the read/write distinction is critical to
correct operation. To distinguish these cases, separate read/write
accessors must be used. This patch migrates (most) remaining
ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following
coccinelle script:
----
// Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and
// WRITE_ONCE()
// $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch
