watchdog: shwdt: fix usage of mod_timer
commit bea1906620ce72b63f83735c4cc2642b25ec54ae upstream.
Fix the usage of mod_timer() and make the driver usable. mod_timer() must
be called with an absolute timeout in jiffies. The old implementation
used a relative timeout thus the hardware watchdog was never triggered.
