Subject: [PATCH] mac80211: Fix sta_mtx unlocking on insert STA failure path

Commit 34e895075e21be3e21e71d6317440d1ee7969ad0 introduced sta_mtx
locking into sta_info_insert() (now sta_info_insert_rcu), but forgot
to unlock this mutex on one of the error paths. Fix this by adding
the missing mutex_unlock() call for the case where STA insert fails
due to an entry existing already. This may happen at least in AP mode
when a STA roams between two BSSes (vifs).
