mac80211: fix a memory leak on sta rate selection table
If the rate control algorithm uses a selection table, it is leaked when the station is destroyed - fix that. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Christophe Prévotaux <cprevotaux@nltinc.com> Fixes: 0d528d85c519 ("mac80211: improve the rate control API") Cc: stable@vger.kernel.org # v3.10+ [add commit log entry, remove pointless NULL check] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
