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