    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
