    features/shard: Fix excessive logging in readdir(p) callback

            Backport of: http://review.gluster.org/#/c/11843/

    On enabling features.shard on a volume which already has few files,
    performing operations on the mount was causing excessive logging of
    messages of the following kind:

    [2015-08-05 10:57:48.743352] E
[shard.c:232:shard_modify_size_and_block_count]
    2-dis-shard: Failed to get trusted.glusterfs.shard.file-size for
    0b2bd401-c438-4d57-8ae5-8d26105d3396

    Turns out this is coming from shard_readdir_cbk() where the shard
    translator unconditionally looks for the xattr
    'trusted.glusterfs.shard.file-size' in every entry's rsp dict and
    logs this error on not finding it. But files that are not sharded
    (i.e., the ones that were created before sharding was enabled on the
volume)
    will not (and should not) have this xattr associated with them.
    So these logs are misleading and must be suppressed in readdir(p).
