Remove IPX over IP tunneling support, which allows IPX routing over IP

tunnels, and was not MPSAFE.  The code can be easily restored in the
event that someone with an IPX over IP tunnel configuration can work
with me to test patches.

This removes one of five remaining consumers of NET_NEEDS_GIANT.
