Quieten hangcheck driver

Every time hangcheck is compiled in it eventually spams the kernel log
with:

Hangcheck: hangcheck value past margin!

This confuses users who usually think it is a generic kernel bug.
Just remove the message. As far as I can see it is useless. The only
value of hangcheck is to reboot the machine if configured.
