[PATCH] netfilter missing symbol has_bridge_parent

5dce971acf2ae20c80d5e9d1f6bbf17376870911 in Linus' tree,
otherwise known as bridge-netfilter-races-on-device-removal.patch in
2.5.15.4 removed has_bridge_parent, however this symbol is still
called with NETFILTER_DEBUG is enabled.

This patch uses the already seeded realoutdev value to detect if a parent
exists, and if so, the value of the parent.
