features/shard: Skip shards resolution if lookup on /.shard returns ENOENT

        Backport of: http://review.gluster.org/#/c/11065

This change is done in [f]truncate, rename, unlink and readv.
Also, this patch also makes lookup in shard delete GF_CONTENT_KEY
as a workaround for the problems with read caching of sparse files
by quick-read. A proper solution would involve shard_lookup_cbk()
performing a readv, aggregating and ordering the responses and setting
it in the xdata before unwinding the response to upper translators, which
will be done in a separate patch.
