Toggle back to zero after setting to one, for consistency.
You don't really want that. It's an extra system call, on a data path
operation.
Yes I do. I don't want 'level' to mean one thing for msi and another
for other interrupts.
If the extra system call ends up hurting, we can add KVM_TOGGLE_IRQ or
define a new level that means 'toggle'.
