Modified Files:
        src/sys/arch/xen/xen: xbd_xenbus.c

Log Message:
(only commit message for rev 1.85, no actual change)

shuffle code in xbd_handler() response loop so that req_bp is never
touched for non I/O responses; unknown commands are now just skipped, also
without touching neither xbdreq, nor req_bp

add some KASSERTS() for xbdreq->req_nr_segments and xbdreq->req_bp,
and reset req_bp after it's processed to ensure the buf can never
be processed twice

intended to simplify debugging in cases like PR port-xen/53506
