Subject: wl12xx: fix a memory leak of probereq template upon recovery
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3eba4a0e6db9ca225bc0f3042d60fcfc86a30bc8;p=openwrt%2Fstaging%2Fblogic.git

wl12xx: fix a memory leak of probereq template upon recovery

wlvif->probereq is zeroed when adding an interface but
the skb pointed to isn't freed when the interface is removed.
This would lead to a mem leak on every recovery.
Fix it by freeing the skb when removing the interface.
