Cancel background scan based roaming behavior if the driver
is capable of handling roaming in the firmware. For fullmac
drivers like ath6kl, the roaming logic is handled in the
firmware and for supplicant to initiate roam, the station
has to disconnect completely and then reconnect with the
new AP which takes a longer time without preauth.

Currently, if the supplicant also tries to roam, all requests
are rejected by cfg80211 resulting in a spam of log.

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.
