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

Log Message:
change xbd_unmap_align() to get the bp via argument rathen than
req_bp, to avoid using req_bp after it's been set to NULL by the
time xbd_unmap_align() is called in xbd_handler(); this fixes
regression caused by previous fix

also make sure xbd_unmap_align() works correctly even when using the
linked request pair for I/O (ie. for Dom0 not supporting indirect
segments), regardless of the order the paired requests finish
