multipath wouldn't autodetect the GROUP_BY_PRIO path grouping policy or
allow the GROUP_BY_TPG policy if there was a path that didn't have its
prioritizer selected (for instance because multipathd was reconfigured
while it was offline). To avoid this, make verify_alua_prio() assume an
alua multipath device if all the paths with a prioritizer selected
(there must be at least one) use an alua-based prioritizer.
