MDCACHE - Fix readdir chunking when reloading chunks

- Track the first and last chunks in a readdir cycle in the readdir
state; this allows reloading the first chunk.
- Track the CK used to reload a chunk. We can't use the first CK, since
that will load the second entry in the chunk.
- When we reload a chunk, skip all the entries in that chunk we already
returned to the caller, to avoid duplicate dirents.
