[libvirt] [PATCH WIP 14/14] nwfilter: remove virt driver callback layer for rebuilding filters

Now that the nwfilter driver keeps a list of bindings that it has created, there is no need for the complex virt driver callbacks. It is possible to simply iterate of the list of recorded filter bindings. This means that rebuilding filters no longer has to acquire any locks on the virDomainObj objects, as they're never touched.
