netdev-dpdk: assume dpdkr peer can be multi-producer/consumer

Browse Source 
Although netdev does explicit locking, it is only valid from the ovs
perspective, then only the ring ends used by ovs should be declared as
single producer/consumer.
The other ends that are used by the application should be declared as
multiple producer/consumer that is the most general case.
