watchdog: imx2_wdt: also set wdog->timeout to new_timeout

Commit faad5de0b104 ("watchdog: imx2_wdt: convert to watchdog core api")
removes the custom ioctl function. The generic ioctl handler is not
setting the wdog->timeout to the new_timeout but handing this preset
value back to the userspace. This patch sets the new value in the
drivers set_timeout function to fix that problem.
