Subject: [PATCH 3.16 068/217] mwifiex: fix corner case association failure

3.16.35-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Amitkumar Karwar <akarwar@...vell.com>

commit a6139b6271f9f95377fe3486aed6120c9142779b upstream.

This patch corrects the error case in association path by returning
-1. Earlier "media_connected" used to remain on in this error case
causing failure for further association attempts.
