[PATCH v0] hamradio: delete unnecessary free_netdev()

[Lin Ma]

The former patch "defer 6pack kfree after unregister_netdev" adds
free_netdev() function in sixpack_close(), which is a bad copy from the
similar code in mkiss_close(). However, this free is unnecessary as the
flag needs_free_netdev is set to true in sp_setup(), hence the
unregister_netdev() will free the netdev automatically.
