Remove double counting HDR_L2ONLY_SIZE

Commit d962d5d didn't quite properly resolve the HDR_L2ONLY_SIZE
accounting.  Accounting is now performed only in the constructor
and destructor which is a nice simplification.  It should have
been removed the from create and destroy functions.  This brings
up back in sync with upstream.
