Set KVM_REQ_EVENT if INIT or SIPI is pending when the guest enables GIF.
INIT in particular is blocked when GIF=0 and needs to be processed when
GIF is toggled to '1'. This bug has been masked by (a) KVM calling
->check_nested_events() in the core run loop and (b) hypervisors toggling
GIF from 0=>1 only when entering guest mode (L1 entering L2).
