Revert change to report interval logic

75acb36 changed the `else` block to an `else if` at line 418 which caused the `pthread_cond_wait` call to fall outside of the block. That resulted in the decision thread blocking without a timeout when a report interval was enabled.

The symptom was not a full freeze of the decision thread, just degraded performance.

The fix is to restore the else so `pthread_cond_wait` falls within the else and is only called when reporting is disabled.
