printk: when dumping regs, show the stack, not thread_info
We currently show: task: <current> ti: <current_thread_info()> task.ti: <task_thread_info(current)>" "ti" and "task.ti" are redundant, and neither is actually what we want to show, which the the base of the thread stack. Change the display to show the stack pointer explicitly.
