KVM: arm/arm64: GICv4: Handle INT command applied to a VLPI
If the guest issues an INT command targetting a VLPI, let's
call into the irq_set_irqchip_state() helper to make it pending
on the physical side.
This works just as well if userspace decides to inject an interrupt
using the normal userspace API...
