[PATCH] convert ipmi_watchdog to use module option nowayout

Convert ipmi_watchdog to also use module option `nowayout' as is done in
other watchdog drivers.

From: Corey Minyard <cminyard@mvista.com>

   The patch is good (same style as other watchdogs), but needs to have
   some documentation updated.  I've tacked that on.
