Subject: panic: clean up message about deprecated 'panic_print' parameter
Date: Tue, 19 Aug 2025 11:51:37 +0200

Remove duplication of the message about the deprecated 'panic_print'
parameter.

Also make the wording more direct. Make it clear that the new
parameters already exist and should be used instead.
