[PATCH net v2] selftests: net: veth: propagate channel-check failures to exit status

[Omokefe Emmanuel Onanaroghene]

chk_channels() reports mismatches with a "fail" line but never sets
ret, so the script exits 0 even when channel counts are wrong. Every
other check helper in the file (__chk_flag, chk_xdp_feature, chk_gro)
sets ret=1 on failure, and all chk_channels() call sites expect the
check to pass. Set ret=1 on mismatch.
