Process RSN pre-authentication candidates when skipping roam

wpa_supplicant_rsn_preauth_scan_results() needs to be called to
update RSN pre-authentication candidates. This cannot be done before
the wpa_supplicant_connect() call on the first association, but when
trying to figure out whether to roam, it is fine to do so for the
case when roaming is skipped.
