Vasily Gorbik 0ab0d7ac20 s390/unwind: correct stack switching during unwind
Adjust conditions in on_stack function. That fixes backchain unwinder
which was unable to read pt_regs at the very bottom of the stack and
hence couldn't follow stacks (e.g. from async stack to a task stack).

Fixes: 78c98f9074 ("s390/unwind: introduce stack unwind API")
