watchdog: Correct watchdog timeout print message

watchdog: Correct watchdog timeout print message

The wdt_start function takes timeout_ms as a parameter and starts the
watchdog with this value. However, when you output the message, it shows
the default timeout value for the watchdog device.
So this patch fixes that part to output the correct timeout value.

Before -->
StarFive # wdt start 3000
WDT:   Started watchdog@13070000 without servicing  (60s timeout)

After -->
StarFive # wdt start 3000
WDT:   Started watchdog@13070000 without servicing  (3s timeout)
