pgsql: Remove useless check for negative result of ip_addrsize().

Remove useless check for negative result of ip_addrsize().

By inspection, ip_addrsize() can't return a negative result.
(If it could, we'd have way bigger problems elsewhere.)
So delete useless check in network_send(). Most C compilers
are probably perfectly capable of removing this code by
themselves, but it's confusing/misleading.
