    features/shard: Fill inode ctx in readdir(p) callback too

            Backport of: http://review.gluster.org/#/c/11854/

    The only place where shard translator was initialising inode ctx
    was lookup callback. But if the inodes are created and linked through
    readdirp, shard_lookup() path _may_ not be exercised before FUSE
    winds other fops on them. Since shard translator does an
    inode_ctx_get() first thing in most fops, an uninitialised ctx could
    cause it to fail the operation with ENOMEM.

    The solution would be to also initialise inode ctx if it has not been
    done already in readdir(p) callback.
