The ovs l2 agent was previously calling get_vif_port_set() on the integration bridge once per rpc_loop() iteration and then again in the periodic _report_state() call that returns the current device count to the neutron service. Since get_vif_port_set() is an expensive call (relying on shell commands) and since there is minimal risk associated with reporting stats that are a few seconds old, this patch caches the device count for reuse by _report_state().
