There are some code in leo_compact_fsm_worker invoking run command more than necessary.
This behavior will result in the degradation of compaction performance.

This issue almost appears when the watchdog communication turns on because its mechanism frequently requests leo_object_storage:increase/1 or leo_object_storage:decrease/1 or leo_object_storage:state/2 during a data-compaction.
