Correct documentation for AF_PACKET (#112339)

Protocol in the address tuple should *not* be in the network-byte-order, because it is converted internally[1].

[1] https://github.com/python/cpython/blob/89ddea4886942b0c27a778a0ad3f0d5ac5f518f0/Modules/socketmodule.c#L2144

network byte order doesn't make sense for a python level int anyways. It's a fixed size C serialization concept.
