Cited commit started returning errors when notification info is not
filled by the bridge driver, resulting in the following regression:
# ip link add name br1 type bridge vlan_filtering 1
# bridge vlan add dev br1 vid 555 self pvid untagged
RTNETLINK answers: Invalid argument
As long as the bridge driver does not fill notification info for the
bridge device itself, an empty notification should not be considered as
an error. This is explained in commit 59ccaaaa49b5 ("bridge: dont send
notification when skb->len == 0 in rtnl_bridge_notify").
Fix by removing the error and add a comment to avoid future bugs.
Fixes: a8db57c1d285 ("rtnetlink: Fix missing error code in rtnl_bridge_notify()")
