target: Remove unnecessary se_task members
This is a squashed version of the following unnecessary se_task structure member removal patches: target: remove the task_execute_queue field in se_task Instead of using a separate flag we can simply do list_emptry checks on t_execute_list if we make sure to always use list_del_init to remove a task from the list. Also factor some duplicate code into a new __transport_remove_task_from_execute_queue helper. target: remove the read-only task_no field in se_task The task_no field never was initialized and only used in debug printks, so kill it. target: remove the task_padded_sg field in se_task This field is only check in one place and not actually needed there. Rationale: - transport_do_task_sg_chain asserts that we have task_sg_chaining set early on - we only make use of the sg_prev_nents field we calculate based on it if there is another sg list that gets chained onto this one, which never happens for the last (or only) task.
