Do not skip MBO PMF check with the WPS special case WPA check exception

Do not skip MBO PMF check with the WPS special case WPA check exception

The MBO PMF check for AP SME in the driver case was added into a
location that is skipped for WPS processing. That was not really the
correct place for this since the skip_wpa_check label was supposed to
remain immediately following the WPA checks. While this does not really
have much of a practical impact, move the check around so that the
skip_wpa_check label remains where it is supposed to be.
