mwifiex: Deactive host sleep using HSCFG after it was activated manually
When powersaving (so either wifi powersaving or deep sleep, depending on
which state the firmware is in) is disabled, the way the firmware goes
into host sleep is different: Usually the firmware implicitely enters
host sleep on the next SLEEP event we get when we configured host sleep
via HSCFG before. When powersaving is disabled though, there are no
SLEEP events, the way we enter host sleep in that case is different: The
firmware will send us a HS_ACT_REQ event and after that we "manually"
make the firmware enter host sleep by sending it another HSCFG command
with the action HS_ACTIVATE.
Now waking up from host sleep appears to be different depending on
whether powersaving is enabled again: When powersaving is enabled, the
firmware implicitely leaves host sleep as soon as it wakes up and sends
us an AWAKE event. When powersaving is disabled though, it apparently
doesn't implicitely leave host sleep, but instead we need to send it a
HSCFG command with the HS_CONFIGURE action and the HS_CFG_CANCEL
condition. We didn't do that so far, which is why waking up from host
sleep was broken when powersaving is disabled.
So add some additional state to mwifiex_adapter where we keep track of
whether host sleep was activated manually via HS_ACTIVATE, and if that
was the case, deactivate it manually again via HS_CFG_CANCEL.
