freeze: If priority is invalid here, it's time to abort

Browse Source 
ctdb_start_freeze() is called from ctdb_control_freeze() which fixes the
priority if it's 0 and return error if it's invalid.  Other callers of
ctdb_start_freeze() are internal to CTDB.  So if priority is invalid in
ctdb_start_freeze(), definitely something is seriously wrong.
