IB/srpt: Remove use of transport_do_task_sg_chain()
With the modern target core, se_cmd->t_data_sg already points to a sglist that covers the whole command. So task_sg chaining is needless overhead and obfuscation -- instead of splicing the split up task sglists back into one list, we can just use the original list directly.
