target: Remove transport_do_task_sg_chain() and associated detritus
Now that all fabrics are converted over to using se_cmd->t_data_sg directly, we can drop the task sg chaining support. With the modern memory allocation in target core, task sg chaining is needless overhead -- we would split up the main cmd sglist into pieces, and then splice those pieces back together instead of just using the original list directly.
