[ Upstream commit d7818402b1d80347c764001583f6d63fa68c2e1a ]

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
