mac80211: fix rx->key NULL pointer dereference in promiscuous mode
commit 1140afa862842ac3e56678693050760edc4ecde9 upstream.
Since:
commit 816c04fe7ef01dd9649f5ccfe796474db8708be5
Author: Christian Lamparter <chunkeey@googlemail.com>

mac80211: consolidate MIC failure report handling
is possible to that we dereference rx->key == NULL when driver set
RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in
promiscuous mode. This happen with rt73usb and rt61pci at least.
Before the commit we always check rx->key against NULL, so I assume
fix should be done in mac80211 (also mic_fail path has similar check).
