Avraham Stern 0288e5e16a cfg80211: avoid double free of PMSR request 
If cfg80211_pmsr_process_abort() moves all the PMSR requests that
need to be freed into a local list before aborting and freeing them.
As a result, it is possible that cfg80211_pmsr_complete() will run in
parallel and free the same PMSR request.

Fix it by freeing the request in cfg80211_pmsr_complete() only if it
is still in the original pmsr list.
