iwlwifi: mvm: don't try to stop scans that are not running anymore

Browse source

In certain conditions, mac80211 may ask us to stop a scan (scheduled
or normal) that is not running anymore.  This can also happen when we
are doing a different type of scan, for instance, mac80211 can ask us
to stop a scheduled scan when we are running a normal scan, due to
some race conditions.  In this case, we would stop the wrong type of
scan and leave everything everything in a wrong state.

To fix this, simply ignore scan stop requests for scans types that are
not running.
