When add lots of (e.g. add 3000) memberships in one multicast group on
ibmveth, the following error message flushes our console log file
8507 [ 901.478251] ibmveth 30000003 env3: h_multicast_ctrl rc=4 when adding
an entry to the filter table
...
1718386 [ 5636.808658] ibmveth 30000003 env3: h_multicast_ctrl rc=4 when adding
an entry to the filter table
We got 1.5 million lines of messages in 1.3h. Let's replace netdev_err() by
netdev_err_ratelimited() to avoid this issue.
