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.
