Letting WARN_ON/WARN_ON_ONCE return the condition means that you could do
if (WARN_ON(blah)) {
handle_impossible_case
}
Rather than
if (unlikely(blah)) {
WARN_ON(1)
handle_impossible_case
}
I checked all the newly added WARN_ON_ONCE users and none of them test the
return status so we can still change it.
