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).
