Fix another set of edge cases where adding a mountpoint or symlink
to the Freelance volume would result in the wrong fid being returned
to the request that made the addition.

When the Freelance directory is updated, invalidate the cm_scache_t object.
that is associated with it.

Actually use the data version when checking callback status.

The return value from Add Mount/Symlink is not negative on failure.
Its an actual error code.  Treat it that way.
