x86, UV: Correct BAU regular message type

The Broadcast Assist Unit messages have a regular or retry
message type. The regular type was not being set, but needs to
be, because the lack of a message type is sometimes used to
identify an unused entry in the message queue.
Also removing some excess comments.
