Commit 51bef03e1a71 ("selftests/net: deflake GRO tests") recently switched to NAPI suspension, and lowered the timeout from 1ms to 100us. This started causing flakes in netdev-run CI. Let's bump it to 200us. In a quick test of a debug kernel I see failures with 100us, with 200us in 5 runs I see 2 completely clean runs and 3 with a single retry (GRO test will retry up to 5 times).
