compaction_manager: fix assertion when stopping task

Browse Source 
Task is stopped by closing gate and forcing it to exit via gate
exception. The problem is that task->compacting_cf may be set to
the column family being compacted, and compaction_manager::remove
would see it and try to stop the same task again, which would
lead to problems. The fix is to clean task->compacting_cf when
stopping task.
