If an exception causes vmexit directly it should not be reported in IDT_VECTORING_INFO during the exit. For that we need to be able to distinguish between exception that is injected into nested VM and one that is reinjected because its delivery failed. Fortunately we already have mechanism to do so for nested SVM, so here we just use correct function to requeue exceptions and make sure that reinjected exception is not moved to IDT_VECTORING_INFO during vmexit emulation and not re-checked for interception during delivery.
