3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Malcolm Priestley <tvbox...@gmail.com>
commit 5e8c3d3e41b0bf241e830a1ee0752405adecc050 upstream.
Don't allow entry to iwctl_siwencodeext if device not open.
This fixes a race condition where wpa supplicant/network manager
enters the function when the device is already closed.
