[PATCH 2.5.70] net-sysfs parent ref count

[Stephen Hemminger <shemminger@xxxxxxxx>]

When creating network sysfs entries, we grab an extra reference to the parent.
Not a big deal now, since it just gets blown away on unregister anyway, but when
kobject reference counts are used for release, things break.
