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

From: Amitkumar Karwar <akarwar@marvell.com>
commit d51246481c7f28bbfa1f814ded2da65e531cd4b2 upstream.
While preparing association request, intersection of device's VHT capability information and corresponding field advertised by AP is used.
This patch fixes a couple errors while saving and copying vht_cap and vht_oper fields from AP's beacon.
