xua: Allow rx DAUD in IPSP with quirk daud_in_asp

That quirk was added back in time most probably when interacting with
some peer who claimed to be in SG mode but actually was in IPSP mode.
Hence, to be on the safe side, be relaxed and allow accepting DAUD also
if the quirk is added, otherwise it may be impossible to continue
communication with that faulty peer.
In theory according to spec DAUD should only be sent ASP->SG.
