gtphub: fix handling of sender from nonstandard port.

Allow a peer sending from an unknown port but a known address, and just
create the port (and unmap the seq nr back to this port later to return
the response to the sender).

Only an SGSN on the Ctrl plane is allowed to make the very first contact
from an unknown address.
