This effectively removes "finally" block so if
authorized_prepared_cache.stop() resolves with exception, the
prepared_cache.stop() is skipped. But that's not a problem -- even if
.stop() throws the shole scylla stop aborts so we don't really care if
it was clean or not.
Also, authorized_prepared_cache.stop() closes the gate and cancels the
timer. None of those can resolve with exception.
