The current method used by detect_prio was selecting the ALUA
prioritizer for devices that didn't have ALUA enabled. This patch
makes detect_prio go through all the steps to get a priority with the
ALUA prioritizer. If it is able to successfully get a priority, then
it selects the ALUA proritizer for the device.
