This is the second version of this series aiming at fixing issues
with vgic-v2 being initialised from non-preemptible context.
* From v1 [1]:
- Repaint kvm_timer_irq_can_fire() to kvm_timer_enabled()
- Drop duplicate kvm_timer_update_status() call
- Force lazy init on the irqfd slow-path for SPIs

KVM: arm64: vgic-v2: Force vgic init on injection outside the run loop
KVM: arm64: vgic-v2: Don't init the vgic on in-kernel interrupt
