[DeviceSanitizer] Only allows to report one error per each kernel launch

When error is detected, the corresponding work-item will exit without
unpoisoning local/private shadow memory. Then other work-items are eary
to cause false alarms. So, we only allows to report one error per each
kernel launch by default.
