KVM: x86: selftests: test simultaneous uses of V_IRQ from L1 and L0
Test that if:
* L1 disables virtual interrupt masking, and INTR intercept.
* L1 setups a virtual interrupt to be injected to L2 and enters L2 with
interrupts disabled, thus the virtual interrupt is pending.
* Now an external interrupt arrives in L1 and since
L1 doesn't intercept it, it should be delivered to L2 when
it enables interrupts.
to do this L0 (abuses) V_IRQ to setup an
interrupt window, and returns to L2.
* L2 enables interrupts.
This should trigger the interrupt window,
injection of the external interrupt and delivery
of the virtual interrupt that can now be done.
* Test that now L2 gets those interrupts.
This is the test that demonstrates the issue that was
fixed in the previous patch.
