KVM: arm64: vgic: Allow last_lr_irq to be NULL when LRs are not overflowing

Browse source

last_lr_irq is always populated when there is any interrupt populated in
the AP list. Not only this is not necessary (it is only useful when we
completely fill the LRs), but this is in the way of further fixes.

Make sure last_lr_irq is kept to NULL when we LRs are not completely
full.
