qed: Revise alloc/setup/free flow
Re-organize the logic that allocates and frees memory of various sub-components of the hw-function - a. No need to pass pointers to said structure as parameters; The internal logic knows exactly where to find/set the data. b. Nullify pointers after cleanup to prevent possible errors to re-entrant code.
