Implement the device API for ufile_hw_cleanup operation, which iterates over the ufile uobjects lists, and attempts to destroy DevX QPs, by issuing up to 8 commands in parallel. This function is responsible only for cleaning the FW resources of the QP, and doesn't necessarily cleanup all of its resources. Hence the normal serialized cleanup flow is still executed after it in __uverbs_cleanup_ufile() to cleanup the remaining resources and handle the cleanup of SW objects. In order to avoid double cleanup for the FW resources, new DevX flag was added DEVX_OBJ_FLAGS_HW_FREED, which marks the object's FW resources as already freed. Since QP destruction is the most time-consuming operation in FW, parallelizing it reduces the cleanup time of applications that use DevX QPs.
