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

Log Message:
use single pre-allocated buffer for unaligned I/O - it's rare and not
performance critical path, it's more important to ensure it will succeed
eventually; also return EAGAIN rather than ENOMEM, so the I/O will be
retried by dk_start() when previous I/O finishes

fix yet another leak on the xengnt_grant_access() fail path in
xbd_diskstart() - this time the unalign buffer
