There are currently two ways in VMX to check if an IRQ or NMI can be
injected:
- vmx_{nmi|irq}_enabled and
- vcpu.arch.{nmi|interrupt}_window_open.
Even worse, one test (at the end of vmx_vcpu_run) uses an inconsistent,
likely incorrect logic.
This patch consolidates and unifies the tests over
{nmi|interrupt}_window_open as cache + vmx_update_window_states
for updating the cache content.
