Subject: [PATCH 1/4] watchdog: hpwdt: Initialize pretimeout from module parameter.

When the pretimeout is specified as a module parameter, the
value should be reflected in hpwdt_dev.pretimeout.  The default
(on) case is correct.  But, when disabling pretimeout, the value
should be set to zero in hpwdt_dev.
