Raphael S. Carvalho afd45b9f49 compaction: Don't leak backlog of input sstable when compaction strategy is changed

The generic backlog formula is: ALL + PARTIAL - COMPACTING

With transfer_ongoing_charges() we already ignore the effect of
ongoing compactions on COMPACTING as we judge them to be pointless.

But ongoing compactions will run to completion, meaning that output
sstables will be added to ALL anyway, in the formula above.

With stop_tracking_ongoing_compactions(), input sstables are never
removed from the tracker, but output sstables are added, which means
we end up with duplicate backlog in the tracker.

By removing this tracking mechanism, pointless ongoing compaction
will be ignored as expected and the leaks will be fixed.

Later, the intention is to force a stop on ongoing compactions if
strategy has changed as they're pointless anyway.
