io_uring task work dispatch makes an indirect call to struct io_kiocb's io_task_work.func field to allow running arbitrary task work functions. In the uring_cmd case, this calls io_uring_cmd_work(), which immediately makes another indirect call to struct io_uring_cmd's task_work_cb field. Change the uring_cmd task work callbacks to functions whose signatures match io_req_tw_func_t. Add a function io_uring_cmd_from_tw() to convert from the task work's struct io_tw_req argument to struct io_uring_cmd *. Define a constant IO_URING_CMD_TASK_WORK_ISSUE_FLAGS to avoid manufacturing issue_flags in the uring_cmd task work callbacks. Now uring_cmd task work dispatch makes a single indirect call to the uring_cmd implementation's callback. This also allows removing the task_work_cb field from struct io_uring_cmd, freeing up 8 bytes for future storage. Since fuse_uring_send_in_task() now has access to the io_tw_token_t, check its cancel field directly instead of relying on the IO_URING_F_TASK_DEAD issue flag.
