Why do we care? Some filesystems don't support i_nlink at all, so it's
always 1. Others won't do the real delete until later (nfs
sillyrename), so returning 0 would be wrong and insane.

So the fact is, expecting 0,0 seems to be an incorrect expectation,
and I don't understand why you would really care. Does it matter?
