Jann Horn f977df7b7c x86/entry/64: Fix unwind hints in rewind_stack_do_exit() 
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.

Fixes: 8c1f75587a ("x86/entry/64: Add unwind hint annotations")
