watchdog: stm32_iwdg: return -ENOSYS on attempt to disable
The stm32_iwdg watchdog can't be disabled. To have the wd commant report
this fact correctly to the user, the ->set_timeout needs to return -ENOSYS
which is interpreted as "Watchdog cannot be disabled" instead of -EINVAL
which means "Timeout value out of range".
