I applied the driver.h and driver_nl80211.c parts to get the new driver
flag for this, but the change to events.c did not look correct, so I
left that out. wpa_supplicant will need quite a bit more changes to be
able to work in ap_scan=2 like way in the default ap_scan=1 mode when
the driver indicates this BSS-selection-in-driver(firmware) capability.
Those changes will take care of not even getting to the
wpa_supplicant_connect(), so there should be no need to modify it in the
way done in this patch.
