Subject: cfg80211/mac80211: disconnect on suspend
If possible that after suspend, cfg80211 will receive request to
disconnect what require action on interface that was removed during
suspend.
Problem can manifest itself by various warnings similar to below one:

[<f8264de1>] __cfg80211_disconnect+0x1b1/0x1d0 [cfg80211]
To fix the problem disconnect from any associated network before
suspend. User space is responsible to establish connection again
after resume. This basically need to be done by user space anyway,
because associated stations can go away during suspend (for example
NetworkManager disconnects on suspend and connect on resume by default).
Patch also handle situation when driver refuse to suspend with wowlan
configured and try to suspend again without it.

Its pretty plainly the result of an skb fragment getting unmapped without having
its initial mapping operation checked for errors. This patch corrects that.

From: Johannes Berg <johannes.berg@intel.com>
When a full scan 2.4 and 5 GHz scan is scheduled, but then the 2.4 GHz
part of the scan disables a 5.2 GHz channel due to, e.g. receiving
country or frequency information, that 5.2 GHz channel might already
be in the list of channels to scan next. Then, when the driver checks
if it should do a passive scan, that will return false and attempt an
active scan. This is not only wrong but can also lead to the iwlwifi
device firmware crashing since it checks regulatory as well.
Fix this by not setting the channel flags to just disabled but rather
OR'ing in the disabled flag. That way, even if the race happens, the
channel will be scanned passively which is still (mostly) correct.
