mac80211: unify SW/offload remain-on-channel
Redesign all the off-channel code, getting rid of
the generic off-channel work concept, replacing
it with a simple remain-on-channel list.
This fixes a number of small issues with the ROC
implementation:
* offloaded remain-on-channel couldn't be queued,
now we can queue it as well, if needed
* in iwlwifi (the only user) offloaded ROC is
mutually exclusive with scanning, use the new
queue to handle that case -- I expect that it
will later depend on a HW flag
The bigger issue though is that there's a bad bug
in the current implementation: if we get a mgmt
TX request while HW roc is active, and this new
request has a wait time, we actually schedule a
software ROC instead since we can't guarantee the
existing offloaded ROC will still be that long.
To fix this, the queuing mechanism was needed.
The queuing mechanism for offloaded ROC isn't yet
optimal, ideally we should add API to have the HW
extend the ROC if needed. We could add that later
but for now use a software implementation.
Overall, this unifies the behaviour between the
offloaded and software-implemented case as much
as possible.

mac80211: do remain-on-channel while idle
The IDLE handling in HW off-channel is broken right
now since we turn off IDLE only when the off-channel
period already started. Therefore, all drivers that
use it today (only iwlwifi!) must support off-channel
while idle, so playing with idle isn't needed at all.
Off-channel in general, since it's no longer used for
authentication/association, shouldn't affect PS, so
also remove that logic.
Also document a small caveat for reporting TX status
from off-channel frames in HW remain-on-channel.

This core is not used by the driver, this patch just makes ssb show the

mac80211: Clear wowlan flag when drv_suspend returns failure
drv_resume can get called without a prior call to drv_suspend.
Consider the following steps:
1. Suspend is started but driver's drv_suspend returns error.
2. Suspend is aborted. local->wowlan flag is left set.
3. Interface is removed.
4. Suspend again. This time open_count is 0 so drv_suspend is
not called and local->wowlan not cleared.
5. On resume ieee80211_reconfig will call drv_resume since
local->wowlan is set.
