But we would be much better to just free it in the caller.  I'ts much
more natural - caller allocates, caller frees, and it's also simpler.

I'll send a patch to do so shortly, together with sorting out the
remaining nfs4d lock_manager_operations abuses.  I think we're set with
that for 2.6.37, the setlease split can wait once we've sorted out the
lock freeing issue.
