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.
