Up until now we never needed to keep a networking locks around representors accesses, we only accessed them when device was reconfigured (under nfp pf->lock) or on fast path (under RCU). Now we want to be able to iterate over all representors during notifications, so make sure representor assignment is done under RTNL lock.

Hi Sasha!
There is no need for backporting this unless 51a6588e8c08 ("nfp: add offloads on representors") is also back ported (which is a feature).
