WPS: Fix ap_scan=2 special association case

Commit 22628eca3440976bf51846da0554099f7429b206 ('Support driver-based
BSS selection in ap_scan=1 mode') ended up disabling the special
ap_scan=2 WPS case where ap_scan=1 like scan followed by association is
used to find the WPS AP using wildcard SSID. Fix this by allowing
association request even with wpas_driver_bss_selection() when searching
for a WPS AP.
