[PATCH wireless-next] wifi: mac80211: fix STA link removal during link removal

[Johannes Berg <johannes@sipsolutions.net>]

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

ieee80211_sta_free_link() only frees the link and doesn't
unhash it, so it can't be used here. Instead this needs
to use ieee80211_sta_remove_link(), which unhashes it. An
argument against it was that it also calls the driver and
that already happened, but calls to the driver removing a
link that's already removed are suppressed, so that's not
actually an issue. Use it to fix the hashtable.
