Before stop wait for start to be finished

Browse Source 
To prevent cache being stopped before async start finialize has finished, stop
routine have to check if worker responsible for finalizing is not running
anymore.

To create link between start finalize and stop functions, work_struct had to be
moved from attach_context to cache_priv.
