[PATCH] Fix IPMI watchdog set_param_str() using kstrdup

[PATCH] Fix IPMI watchdog set_param_str() using kstrdup

set_param_str() cannot use kstrdup() to duplicate the parameter.  That's
fine when the driver is compiled as a module but it sure is not when built
into the kernel as the kernel parameters are parsed before the kmalloc
slabs are setup.
