mac80211: initialize sta pointer to avoid false-positive warning
Some compilers (eg. gcc 4.4.1 for ARM) report a false positive warning
in mlme.c:
net/mac80211/mlme.c: In function 'ieee80211_prep_connection':
net/mac80211/mlme.c:3035: warning: 'sta' may be used uninitialized in this function
This is a false positive because the place where 'sta' is used is
inside an if with the same condition of where it is set:
[...]
if (!have_sta) {
sta = sta_info_alloc(sdata, cbss->bssid, GFP_KERNEL);
if (!sta)
return -ENOMEM;
}
[...]
if (!have_sta) {
[...]
sta->sta.supp_rates[cbss->channel->band] = rates;
[...]
For some reason the compiler doesn't understand this and warns.
While this is not a problem in the code itself, we can avoid polluting
the build logs with false positives by setting sta to NULL on
declaration and checking for sta instead of !have_sta in the second if.

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.

while idle, so playing with idle isn't needed at all.
Off-channel in general, since it's no longer used for

also remove that logic.
