kobj_uevent: Ignore if some listeners cannot handle message
commit ebf4127cd677e9781b450e44dfaaa1cc595efcaa upstream.
kobject_uevent() uses a multicast socket and should ignore
if one of listeners cannot handle messages or nobody is
listening at all.
Easily reproducible when a process in system is cloned
with CLONE_NEWNET flag.
