[PATCH bpf-next v4 14/14] selftests/bpf: Use make_sockaddr in ip_check_defrag

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

This patch uses public helper make_sockaddr() exported in network_helpers.h
instead of open-coding in test_bpf_ip_check_defrag_ok() in
prog_tests/ip_check_defrag.c. This can avoid duplicate code.
