watchdog: iTCO_wdt: Update the heartbeat value after clamping timeout
When executing "modprobe iTCO_wdt heartbeat=700", the user-specified
'heartbeat' parameter exceeds the valid range, the driver clamps the
timeout to default 30s but fails to update the logged 'heartbeat' value,
resulting in misleading log output:
iTCO_wdt iTCO_wdt: timeout value out of range, using 30
iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0)
After validating the range, update the 'heartbeat' value with the clamped
timeout value to ensure that log messages accurately reflect the actual
runtime parameters.
