    For CRC enabled v5 super block, change a file's ownership can simply
    trigger an ASSERT failure at xfs_setattr_nonsize() if both group and
    project quota are enabled, i.e,
    
    [  305.337609] XFS: Assertion failed: !XFS_IS_PQUOTA_ON(mp), file: fs/xfs/xfs_iops.c, line: 621

    This fix adjust the assertion to check if the super block support both
    quota inodes or not.
