Subject: [PATCH 3.14 1/2] mwifiex: copy AP's HT capability info correctly

From: Amitkumar Karwar <[email protected]>

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.
