Subject: [PATCH] making upcall wait uninterruptable

switching user's upcall wait from being UserMode and TRUE (interruptable) to KernelMode and FALSE. msdn doc does recommend for simplicity of the drivers to do that.

it seems to no longer generate interrupts on close irps but we are still able to ctrl-c running tests.
