    fs/ext4: removed FS_VIRTUALIZED flag from 'ext3' mode of ext4 module
    
    FS_VIRTUALIZED flag makes a registered filesystem visible in container.
    ext3 is part of ext4 module that is run with untested set of flags.

    khorenko@: this flag allows to mount ext3 fs inside a Container
    if a Container has proper permissions for a device to be mounted.
    In vz7 we never allowed it, we don't test it, so don't see any
    advantages of enabling it in vz8. We can change this of course upon
    request.
