It must remove itself from the compaction_manager,
that will stop_ongoing_compactions.

Without that we're hitting
```
sstable_compaction_test: ./seastar/include/seastar/core/gate.hh:56: seastar::gate::~gate(): Assertion `!_count && "gate destroyed with outstanding requests"' failed.
```

when destroying the compaction_manager.
