Peter Xu 36adac4934 kvm: Introduce slots lock for memory listener 
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.
