arm64: traps: simplify die() and __die() In arm64's die and __die routines we pass around a thread_info, and subsequently use this to determine the relevant task_struct, and the end of the thread's stack. Subsequent patches will decouple thread_info from the stack, and this approach will no longer work. To figure out the end of the stack, we can use the new generic end_of_stack() helper. As we only call __die() from die(), and die() always deals with the current task, we can remove the parameter and have both acquire current directly, which also makes it clear that __die can't be called for arbitrary tasks.
