    xfs: do not check NEEDSREPAIR if ro,norecovery mount.

    If there is corrutpion on the filesystem andxfs_repair
    fails to repair it. The last resort of getting the data
    is to use norecovery,ro mount. But if the NEEDSREPAIR is
    set the filesystem cannot be mounted. The flag must be
    cleared out manually using xfs_db, to get access to what
    left over of the corrupted fs.
