hv: vlapic: wrap APICv check pending delivery interrupt

Browse Source 
When in fully APICv mode, we enable VID. All pending delivery interrupts
will inject to VM before VM entry. So there is no pending delivery interrupt.
However, if VID is not enabled, we can only inject pending delivery interrupt
one by one. So we always need to do this check.
