It probably means nothing: this is a typical termination condition when
reading from a recycled WAL file. You come to a page that doesn't have
the expected page address, because what it's got is whatever it had in
the WAL file's previous cycle of life.
The PANIC is evidently happening during post-WAL-scanning cleanup,
perhaps while we're trying to repair incomplete btree page splits
or some such. But I don't want to speculate too much without a
stack trace.
