[PATCH v3 2/2] selftests/net: replace ternary operator with min()/max()

[Mahmoud Maatuq <mahmoudmatook.mm@gmail.com>]

Fix the following coccicheck warning:
tools/testing/selftests/net/udpgso_bench_tx.c:297:18-19: WARNING opportunity for min()
tools/testing/selftests/net/udpgso_bench_tx.c:354:27-28: WARNING opportunity for min()
tools/testing/selftests/net/so_txtime.c:129:24-26: WARNING opportunity for max()
tools/testing/selftests/net/so_txtime.c:96:30-31: WARNING opportunity for max()

Signed-off-by: Mahmoud Maatuq <mahmoudmatook.mm@gmail.com>
---
changes in v3:
remove Suggested-by tag
fix wrong comment inside selftests/net/Makefile

changes in v2:
cast var cfg_mss to int to avoid static assertion
after providing a stricter version of min() that does signedness checking.
