kasan: check object_size in kasan_complete_mode_report_info

Check the object size when looking up entries in the stack ring.

If the size of the object for which a report is being printed does not
match the size of the object for which a stack trace has been saved in the
stack ring, the saved stack trace is irrelevant.
