nfp: add locking around representor changes
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.
