Subject: [PATCH 4.4 29/51] mwifiex: correct aid value during tdls setup

4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Xinming Hu <huxm@...vell.com>

commit b64db1b252e9974a43a51ba083fa7d03e4716167 upstream.

AID gets updated during TDLS setup, but modified value isn't reflected
in "priv->assoc_rsp_buf". This causes TDLS setup failure. The problem is
fixed here.

Fixes: 4aff53ef18e4a4 ("mwifiex: parsing aid while receiving..")
