    Revert "features/shard: Make o-direct writes work with sharding"

    This reverts commit c272c71391cea9db817f4e7e38cfc25a7cff8bd5.

    This is for two reasons:
    1) It introduces high fop latencies
    2) Even with the patch, there is no true odirect behavior since the
       workaround in the patch doesn't reduce the caching done in kernel's
       page cache as far as writes on anon fds associated with individual
       shards is concerned.
