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.
Fixes: c017800af5c71 ("selftests: net: veth: test peer ndo-xmit after GRO toggle while down")

The Fixes tag should point to the commit that added chk_channels():
Fixes: 1ec2230fc721 ("selftests: net: veth: add tests for set_channel")
c017800af5c7 did not change this helper. The bug is present since
v5.15.
