    features/shard: Eliminate extra update to postbuf in writev

    After an extending write is complete, shard translator updates postbuf
    at two places:
    1. shard_update_file_size_cbk(), and
    2. shard_post_update_size_writev_handler().

    This can lead to unexpected behavior if md-cache is part of the client
    stack and caches and serves values returned by shard translator in
    postbuf. This patch eliminates the update to postbuf in
    shard_post_update_size_writev_handler().
