Subject[PATCH 3.2 011/115] mac80211: fix memory leak
3.2.80-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Sudip Mukherjee <sudip@vectorindia.org>

commit ea32f065bd3e3e09f0bcb3042f1664caf6b3e233 upstream.

On error we jumped to the error label and returned the error code but we
missed releasing sinfo.

Fixes: 5fe74014172d ("mac80211: avoid excessive stack usage in sta_info")

[bwh: Backported to 3.2: there's no out_err label but there is another
error case that would leak sinfo]
