Process pending events on nested VM-Exit if the vCPU has an injectable IRQ or NMI, as the event may have become pending while L2 was active, i.e. may not be tracked in the context of vmcs01. E.g. if L1 has passed its APIC through to L2 and an IRQ arrives while L2 is active, then KVM needs to request an IRQ window prior to running L1, otherwise delivery of the IRQ will be delayed until KVM happens to process events for some other reason. The missed failure is detected by vmx_apic_passthrough_tpr_threshold_test in KVM-Unit-Tests, but has effectively been masked due to a flaw in KVM's PIC emulation that causes KVM to make spurious KVM_REQ_EVENT requests (and apparently no one ever ran the test with split IRQ chips).
