Upgrade and rate-limit compression failure message.

Without this message getting logged at 'WARN', it's hard to contextualize the messages we get about compression bombs, so this message should fix #40175 (closed).

I'm rate-limiting this, however, since it could get spammy if somebody on the network starts acting up. (Right now it should be very quiet; I've asked Sebastian to check it, and he says that he doesn't hit this message in practice.)

Closes #40175 (closed).

We should test this out in 0.4.6 first before we backport all the way to 0.4.5.
