watchdog: Don't require WDIOC_SETOPTIONS/WDIOS_ENABLECARD
Not all watchdog drivers implement WDIOC_SETOPTIONS. Drivers which do not implement it have their device always enabled. So it's fine to report an error if WDIOS_DISABLECARD is passed and the ioctl is not implemented, however failing when WDIOS_ENABLECARD is passed and the ioctl is not implemented is not good: if the device was already enabled then WDIOS_ENABLECARD was a no-op and wasn't needed in the first place. So we can just ignore the error and continue.
