kasan: rearrange stack frame info in reports

Browse source

- Move printing stack frame info before printing page info.

 - Add object_is_on_stack() check to print_address_description() and add
   a corresponding WARNING to kasan_print_address_stack_frame(). This
   looks more in line with the rest of the checks in this function and
   also allows to avoid complicating code logic wrt line breaks.

 - Clean up comments related to get_address_stack_frame_info().
