When a vPE exits, the pending_last flag is set when there are
pending VLPIs stored in the pending table. Similarily, we set
this flag when a doorbell interrupt fires, as it indicates the
same condition.
Let's update kvm_vgic_vcpu_pending_irq() to account for that
flag as well, making a vcpu runnable when set.
