lcr: remove excessive conditional check in do_from_gw()

After an update of the bsearch(), which now supports matching not only
by the IP address, but also using the 'src_port', there is no need to check,
if the source port of a request matched the one from the 'lcr_gw'
('res' pointer will be NULL anyway, if ports don't match).

Nor do we need to check if it's zero.
