[PATCH 4.4 43/48] mac80211: fix memory leak

[Greg Kroah-Hartman]

From: Sudip Mukherjee <su...@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")
