From: Felix Fietkau <nbd@xxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 53d045258ee2e38b1e882617cb0799a04d05f5fa upstream.
If the rate control algorithm uses a selection table, it
is leaked when the station is destroyed - fix that.

Fixes: 0d528d85c519 ("mac80211: improve the rate control API")
