KVM: arm64: Allow no running vcpu on restoring vgic3 LPI pending status
We don't have a running VCPU context to restore vgic3 LPI pending status
due to command KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_RESTORE_TABLES} on KVM
device "kvm-arm-vgic-its".
Use vgic_write_guest_lock() to restore vgic3 LPI pending status.
