[PATCH 2/7] KVM: arm/arm64: vgic-v3: Clear all dirty LRs

[Marc Zyngier]

From: Christoffer Dall <christoffer.dall at linaro.org>

When saving the state of the list registers, it is critical to
reset them zero, as we could otherwise leave unexpected EOI
interrupts pending for virtual level interrupts.
