ip_gre.c in 2.6.0-test5

Hi all,
this trivial patch fixes possible kernel crash when using GRE tunnels in 2.6.0-test. The problem was that "dev->init" wasn't set before register_netdevice() call and so the initialization function was never called. Consequently some fields in the tunnel structure were not initialized what finally led to a kernel crash upon receiving the first packet over the GRE tunnel.
