6977fc05d9 VMX: adjust RFLAGS saved into guest state on VMEXIT according to VMX documentation: 
For APIC-access VM exits and for VM exits caused by:
- EPT violations
- EPT misconfigurations
- page-modification log-full events or
- SPP-related events
the value saved depends on whether the VM exit occurred during delivery of an event through the IDT ...

also handle RFlags saved if VMEXIT was caused directly by an event that would normally be delivered through the IDT

should fix #215
