Since returning less directory data than requested is not a problem for FreeBSD and even UFS no longer returns directory structures with d_fileno == 0, this patch stops the client from doing this. Although entries with d_fileno == 0 should not be a problem, the man pages no longer document that these entries should be ignored, so there was a concern that these entries might be an issue in the future.
