The kopald thread handles opal events as they appear, but by polling a static bit-vector in last_outstanding_events. Annotate these data races accordingly. We are not at risk of missing events, but use of READ_ONCE, WRITE_ONCE will assist readers in seeing that kopald only consumes the events it is aware of when it is scheduled. Also removes extraneous KCSAN warnings.
