Subject: iwlwifi: mvm: don't WARN when statistics are handled late
From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
commit 1e9291996c4eedf79883f47ec635235e39d3d6cd upstream.
Since the statistics handler is asynchrous, it can very well
be that we will handle the statistics (hence the RSSI
fluctuation) when we already disassociated.
Don't WARN on this case.
This solves: https://bugzilla.redhat.com/show_bug.cgi?id=1071998
