Allow async transfer negotiation updates to modify tagging behavior.

Browse Source 
The XPT uses this to prevent tags from being used on parallel SCSI
interfaces immediately after a bus reset or BDR so that controllers
have an oportunity to renegotiate without tag messages in the way.
Somehow this got disabled... the functionality has been here for
quite some time.
