Summary

We introduced a log message "skipping compaction" in WT-10897 when compact decides that there is no useful work to do for the table. Unfortunately, the message still gets sometimes logged even if compact does some work.

Diagnosis

The message is logged from within _wt_compact when there is no work to do, but that does not account for the fact that wt_compact is called in a loop from _compact_worker in session_compact.c. We need to log this message only if first iteration decides that there is no work to do.
