6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit 06a093807eb7b5c5b29b6cff49f8174a4e702341 ]
If the rx payload length check fails, or if kmemdup() fails,
we still need to free the command response. Fix that.
Fixes: 21254908cbe9 ("iwlwifi: mvm: add RFI-M support")
