wifi: mac80211: ibss: mark IBSS left before leaving

Mark that we left the IBSS before actually leaving (which
requires calling the driver). Otherwise, it's possible to
have the driver do some work flushing etc. while leaving,
and then get into the work trying to join again while all
data is being destroyed.
