KVM: VMX: Disallow NMI while blocked by STI
While not mandated by the spec, Linux relies on NMI being blocked by an IF-enabling STI. VMX also refuses to enter a guest in this state, at least on some implementations. Disallow NMI while blocked by STI by checking for the condition, and requesting an interrupt window exit if it occurs.
