Introduce KVMMemoryListener.slots_lock to protect the slots inside the kvm memory listener. Currently it is close to useless because all the KVM code path now is always protected by the BQL. But it'll start to make sense in follow up patches where we might do remote dirty bitmap clear and also we'll update the per-slot cached dirty bitmap even without the BQL. So let's prepare for it. We can also use per-slot lock for above reason but it seems to be an overkill. Let's just use this bigger one (which covers all the slots of a single address space) but anyway this lock is still much smaller than the BQL.
