[PATCH] panic: Clean up message about deprecated 'panic_print' parameter

[Petr Mladek <pmladek@suse.com>]

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.
