Paolo Bonzini 7e7126846c kvm: nVMX: fix entry with pending interrupt if APICv is enabled 
Commit b5861e5cf2 introduced a check on
the interrupt-window and NMI-window CPU execution controls in order to
inject an external interrupt vmexit before the first guest instruction
executes.  However, when APIC virtualization is enabled the host does not
need a vmexit in order to inject an interrupt at the next interrupt window;
instead, it just places the interrupt vector in RVI and the processor will
inject it as soon as possible.  Therefore, on machines with APICv it is
not enough to check the CPU execution controls: the same scenario can also
happen if RVI>vPPR.
