Correctly calculate the value to put in the imx wdog countdown register.

The correct value is seconds*2-1.  The code was using just seconds*2, which
led to being off by a half-second -- usually not a big deal, except when the
value was the max (128) it overflowed so zero would get written to the
countdown register, which equates to a timeout of a half second.
