Subject: [PATCH 115/141] md-cache: Enable caching of stat fetched from readdirp

Patch http://review.gluster.org/11894 removed readdirp fop for
md-cache, but there is no mention of exact xlator which was
failing because of this. As mentioned by Rafi(author of patch 11894)
tiering and svc doesn't really need this as the inode_ctx is populated
in readdirp_cbk. Hence reverting this commit.
This reverts commit c8c9308134ae4ce24c630a1b0ccfcf4e8f9b0fe7.
