    f2fs: fix to check compress file in f2fs_move_file_range()
    
    [ Upstream commit fb9b65340c818875ea86464faf3c744bdce0055c ]
    
    f2fs_move_file_range() doesn't support migrating compressed cluster
    data, let's add the missing check condition and return -EOPNOTSUPP
    for the case until we support it.
