====================
selftests: Fix udpgro failures

There are 2 issues for the current udpgro test. The first one is the testing
doesn't record all the failures, which may report pass but the test actually
failed. e.g.
https://netdev-3.bots.linux.dev/vmksft-net/results/725661/45-udpgro-sh/stdout



The other one is after commit d7db7775 ("net: veth: do not manipulate
GRO when using XDP"), there is no need to load xdp program to enable GRO
on veth device.
