Subject: [PATCH 3.2 163/200] mwifiex: copy AP's HT capability info correctly

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

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

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

commit c99b1861c232e1f641f13b8645e0febb3712cc71 upstream.

While preparing association request, intersection of device's HT
capability information and corresponding fields advertised by AP
is used.

This patch fixes an error while copying this field from AP's
beacon.
