Dmitry Antipov 301268dbaa wifi: carl9170: do not ping device which has failed to load firmware 
[ Upstream commit 15d2530769 ]

Syzkaller reports [1, 2] crashes caused by an attempts to ping
the device which has failed to load firmware. Since such a device
doesn't pass 'ieee80211_register_hw()', an internal workqueue
managed by 'ieee80211_queue_work()' is not yet created and an
attempt to queue work on it causes null-ptr-deref.
