    f2fs: Only lfs mode is allowed with zoned block device feature
    
    [ Upstream commit 2bd4df8fcbc72f58ce3c62ed021ab291ca42de0b ]
    
    Now f2fs support four block allocation modes: lfs, adaptive,
    fragment:segment, fragment:block. Only lfs mode is allowed with zoned block
    device feature.
