Subject: mac80211: free netdev on dev_alloc_name() error

From: Johannes Berg <johannes.berg@intel.com>


[ Upstream commit c7a61cba71fd151cc7d9ebe53a090e0e61eeebf3 ]

The change to remove free_netdev() from ieee80211_if_free()
erroneously didn't add the necessary free_netdev() for when
ieee80211_if_free() is called directly in one place, rather
than as the priv_destructor. Add the missing call.

Fixes: cf124db566e6 ("net: Fix inconsistent teardown and release of private netdev state.")
