Windows: Report actual volume creation time

The cm_scache.volumeCreationDate is populated by any non-bulkstat
callback issuing operation.  If it is not set at the time the
redirector requests volume information, force an RXAFS_FetchStatus
and then use the resulting timestamp in the response.

Windows: Claim success for Delete Reparse Tag

The typical pattern for deleting a reparse point is

 1. open reparse point object
 2. delete reparse tag
 3. set delete on close
 4. close handle

Claim success when we receive delete reparse tag fsctl so that
the delete on close disposition can be set.
