net/ring: fix adding MAC addresses

When .mac_addr_add() was changed to allow a return code, ring was changed
to return -ENOTSUP.  This changes the behavior of the rte_ring driver in
a way that does not maintain backward compatibility.  Additionally, if
the intent is to return -ENOTSUP, you could simply not define the stubs.
