[XFS] kill BMAPI_UNWRITTEN
There is no reason to go through xfs_iomap for the BMAPI_UNWRITTEN because
it has nothing in common with the other cases. Instead check for the
shutdown filesystem in xfs_end_bio_unwritten and perform a direct call to
xfs_iomap_write_unwritten (which should be renamed to something more
sensible one day)
