trafgen: l3: Support interface without IP address

Move default source address setting to packet_finish so that we do not
need to get the device's address if the source address is set in the
packet. Without this, trafgen does not work with an interface without
address configured. In addition, in the case failing to get the address
for an interface, intead of panic, it now prints a warning and uses a
value of 0.0.0.0.
