Defer updating SVI (i.e. the VMCS's highest ISR cache) when L2 is active,
but L1 has not enabled virtual interrupt delivery for L2, as an EOI that
is emulated _by KVM_ in such a case acts on L1's ISR, i.e. vmcs01 needs to
reflect the updated ISR when L1 is next run.

Note, L1's ISR is also effectively L2's ISR in such a setup, but because
virtual interrupt deliver is disable for L2, there's no need to update
SVI in vmcs02, because it will never be used.
