Nah, it's not redundant, we need to check for potential L2->L2 switches
*before* trying deliver events to L2.
Yeah, and after the call in inject_pending_event you can similarly have
an "else if" since vmx_nmi/interrupt_allowed will check
nested_run_pending and never return true.
But think I can (and probably
should) get rid of the second test in vcpu_enter_guest.
If so inject_pending_event would return true to request an immediate
exit, right?
