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.
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.
