mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scan
For client STA interfaces, ieee80211_do_stop unsets the relevant
interface's SDATA_STATE_RUNNING state bit prior to cancelling an
interrupted scan. When ieee80211_offchannel_return is invoked as
part of cancelling the scan, it doesn't bother unsetting the
SDATA_STATE_OFFCHANNEL bit because it sees that the interface is
down. Normally this doesn't matter because when the client STA
interface is brought back up, it will probably issue a scan. But
in some cases (e.g., the user changes the interface type while it
is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This
prevents the interface queues from being started. So we
cancel the scan before unsetting the SDATA_STATE_RUNNING bit.
