SWDEV-79445 - OCL generic changes and code clean-up
	- Following CL#1552596. Add a flag to skip memory allocation. ROCr backend requires access to the parent object in the blit manager, but it's not fully initialized and a view creation is required. However a view creation with not fully initialized object can cause a dead lock if device memory is allocated during the object create.
