[PATCH 2.5.70] net-sysfs parent ref count

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.

   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.

Applied, thanks.
