ipmr: Call ->dellink() to remove DVMRP tunnel device.

Browse source

ipmr.c uses unregister_netdevice() to remove DVMRP tunnel devices
created in ipmr_new_tunnel().

This is fine because currently ip_tunnel_uninit() also calls
ip_tunnel_del() to unlink the device from the hash table.

However, we will move ip_tunnel_del() from ip_tunnel_uninit() to
ip_tunnel_dellink().

Removing DVMRP tunnel devices by unregister_netdevice() would leave
them in the hash table.

Let's call ->dellink for DVMRP tunnel devices.
