Avoid adding mngt_queue to io_queues list

Browse Source 
Previously every created queue was added to io_queues list, which
made mngt_queue being used in ocf_parallelize. Change mngt_queue creation
API so that mngt_queue is not added to the list and doesn't have
unnecessary functionalities initialized.
