[PATCH 339/641] Staging: hv: warn the world of a bug in the release function

All device release functions need to do something, if not, it's a bug.
By merely providing an "empty" release function, it gets the kernel to
shut up, but that's not solving the problem at all. Stick a big fat
WARN_ON(1); in there to get people's attention.
