mac80211: cancel/restart all timers across suspend/resume
We forgot to cancel all timers in mac80211 when suspending. In particular we forgot to deal with some things that can cause hardware reconfiguration -- while it is down. While at it we go ahead and add a warning in ieee80211_sta_work() if its run while the suspend->resume cycle is in effect. This should not happen and if it does it would indicate there is a bug lurking in either mac80211 or mac80211 drivers. With this now wpa_supplicant doesn't blink when I go to suspend and resume where as before there where issues with some timers running during the suspend->resume cycle. This caused a lot of incorrect assumptions and would at times bring back the device in an incoherent, but mostly recoverable, state. Signed-off-by: Luis R.
