Subject: iwlwifi: mvm: free RX reorder buffer on restart
From: Sara Sharon <[email protected]>
commit 60dec5233cd8651860e8010c953d116fb0f1ba86 upstream.
Restart flow zeroes the rx_ba_sessions counter. Mac80211 asks driver to tear down of the session only afterwards, and as a result driver didn't free the data. Fix it.
