selftests: KVM: testing the local IRQs resets
Local IRQs are reset by a normal cpu reset. The initial cpu reset and the clear cpu reset, as superset of the normal reset, both clear the IRQs too. Let's inject an interrupt to a vCPU before calling a reset and see if it is gone after the reset. We choose to inject only an emergency interrupt at this point and can extend the test to other types of IRQs later.
