netpoll: Consolidate neigh_tx processing in service_neigh_queue
Move the bond slave device neigh_tx handling into service_neigh_queue. In connection with neigh_tx processing remove unnecessary tests of a NULL netpoll_info. As the netpoll_poll_dev has already used and thus verified the existince of the netpoll_info. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S.
