I noticed a couple problems with the lease patches. Also:

We still need to do this part. I just did the minimum required to fix
the problem--I figure splitting out a separate ->delete_lease method
(which I agree would be cleaner) could wait till the next merge window.
Patches follow, tested on top of the merge of Arnd's patches; if they
look OK they can go in, or I can commit them on top of a few pending
nfsd fixes and send another pull request.
It'd be nice if we get this fixed by -rc1, but not the end of the world
if we don't.
