 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
