[ARP]: Remove overkill checks from neigh_param_alloc.
Valid network device is always passed into neigh_param_alloc, so remove extra checking for dev == NULL. Additionally, cleanup bogus netns assignment. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
