6.10-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 7167395a4be7930ecac6a33b4e54d7e3dd9ee209 ]
Currently, we only check the latest senders's exit code. If the receiver report failed, it is not recoreded. Fix it by checking the exit code of all the involved processes.
Before: 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 $ echo $? 0
After: 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 $ echo $? 1
