Jann Horn 5c45893130 x86/entry/64: Fix unwind hints in rewind_stack_do_exit()

commit f977df7b7ca45a4ac4b66d30a8931d0434c394b1 upstream.

The LEAQ instruction in rewind_stack_do_exit() moves the stack pointer
directly below the pt_regs at the top of the task stack before calling
do_exit(). Tell the unwinder to expect pt_regs.
