amcheck: Report an error when the next page to a leaf is not a leaf
This is a very unlikely condition during checking a B-tree unique constraint,
meaning that the index structure is violated badly, and we shouldn't continue
checking to avoid endless loops, etc. So it's worth immediately throwing an
error.
