Log Message:
rump: Handle uvm_wait tickets like the real kernel does.

This should avoid trouble in any path that calls uvm_wait_prepare
with spin locks held even though it's not going to sleep in uvm_wait,
of which there are probably many more than just rump_hypermalloc --
uvm_wait_prepare is supposed to be cheap enough not to be worth
conditionalizing.  (Perhaps we should measure that, though.)
