[NET]: Call uninit if necessary in register_netdevice

Browse Source 
This patch makes register_netdevice call dev->uninit if the regsitration
fails after dev->init has completed successfully.  Very few drivers use
the init/uninit calls but at least one (drivers/net/wan/sealevel.c) may
leak without this change.
