Subject[068/262] kobj_uevent: Ignore if some listeners cannot handle message
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Milan Broz <mbroz@redhat.com>

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.
