[RTNETLINK]: Remove unnecessary locking in dump callbacks
Since we're now holding the rtnl during the entire dump operation, we can remove additional locking for rtnl protected data. This patch does that for all simple cases (dev_base_lock for dev_base walking, RCU protection for FIB rule dumping). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
