Detach finish: destroy stop pipeline before cmpl

Browse Source 
'stop_pipeline' filed may be reused during cache lifetime (e.g. when cache is
detached and attached again - the pipeline would be freed and then
re-allocated). Calling completion after detach before freeing the pipeline may
lead to race condition.
