vt6655: Fix late setting of byRFType.

commit 1f51d58 upstream. byRFType is not set prior to registration of mac80211 causing unpredictable operation after channel scans. With byRFType unset all channels are enabled this causes tx power to be set to values not present its eeprom. Move setting of this variable to vt6655_probe. byRFType must have a mask set. byRevId not used by driver and is removed.
