selftests: udpgro: no need to load xdp for gro
After commit d7db7775ea2e ("net: veth: do not manipulate GRO when using
XDP"), there is no need to load XDP program to enable GRO. On the other
hand, the current test is failed due to loading the XDP program. e.g.
# selftests: net: udpgro.sh
# ipv4
# no GRO ok
# no GRO chk cmsg ok
# GRO ./udpgso_bench_rx: recv: bad packet len, got 1472, expected 14720
#
# failed
[...]
# bad GRO lookup ok
# multiple GRO socks ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
#
# ./udpgso_bench_rx: recv: bad packet len, got 1452, expected 14520
#
# failed
ok 1 selftests: net: udpgro.sh
After fix, all the test passed.
# ./udpgro.sh
ipv4
no GRO ok
[...]
multiple GRO socks ok
