mm/damon/core: fix return value from damos_wmark_metric_value
damos_wmark_metric_value's return value is 'unsigned long', so returning
-EINVAL as 'unsigned long' may turn out to be very different from the
expected one (using 2's complement) and treat as usual matric's value.
So, fix that, checking if returned value is not 0.
