trafgen: l3: Fix checksum for UDP/TCP protos
While fixing the issue with getting of IPv4 address from device,
the setting of default src IPv4/IPv6 addresses was moved from
hdr->header_init(...) callback to hdr->packet_finish(...), but
packet_finish(...) is called in the following order:
udp_hdr->packet_finish() - UDP csum calculation over IPv4/6 pseudo header
ip4_hdr->packet_finish() - setting default src IPv4 address from dev
...
So src IPv4/6 address will be set after UDP/TCP csum calculation which
is wrong, so fixed issue by moving it to the hdr->header_init(...) stage
as it was before the c4e07d5142c8.
Fixes: c4e07d5142c8 ("trafgen: l3: Support interface without IP address")
