Hong zhi guo 7b99a99390 bridge: avoid br_ifinfo_notify when nothing changed
When neither IFF_BRIDGE nor IFF_BRIDGE_PORT is set,
and afspec == NULL but  protinfo != NULL, we run into
"if (err == 0) br_ifinfo_notify(RTM_NEWLINK, p);" with
random value in ret.

Thanks to Sergei for pointing out the error in commit comments.
