Subject: KVM: arm/arm64: vgic-v2: Clear all dirty LRs

From: Christoffer Dall <[email protected]>

commit 4d3afc9bad2b67b118a0cc204dc94703f7a44e74 upstream.

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.
