Do not copy STA VHT capabilities if VHT is not enabled for AP
Previously, station's VHT information elements were copied and passed
regardless of the AP's VHT configuration. As a result, AP with VHT
disabled in configuration could have ended up transmitting packets in
VHT rates though AP is not advertising VHT support. Fix this by copying
the station's VHT capabilities only when AP supports VHT (both hardware
and configuration).
