description:
entropy: Downgrade consolidation warning from printf to LOG_DEBUG.

Candidate fix for PR kern/55458.  This message is rather technical,
and so is unlikely to be acted on by anyone not debugging the kernel
anyway.  Most likely, on any system where it is a real problem, there
will be another (less technical) entropy warning anyway.
