The mmu_notifier_retry is not specific to any vcpu (and never will be)
so only take struct kvm as a parameter.
The motivation is the ARM mmu code that needs to call this from
somewhere where we long let go of the vcpu pointer.

device with virtualiation extensions into the guest address space.
We try to make this API slightly more generic than for our specific use,
but so far only the VGIC uses this feature.

The solution is to examine already active LRs, and check the
interrupt is still enabled. If not, just retire it.
