sgsn: Simplify finding/using the first address of the result

The loop was used to print all returned addresses but we can
simply pick the first one. This is fixing a coverity issue that
the loop will be executed eaxactly once (and that was on
purpose).

Simplify the code and just take the first element (which might
be NULL).
