6lowpan: fix debugfs interface entry name

This patches moves the debugfs interface related register after netdevice register. The function lowpan_dev_debugfs_init will use "dev->name" which can be before register_netdevice a format string. The function register_netdevice will evaluate the format string if necessary and replace "dev->name" to the real interface name.
