nbtree: Demote incomplete split "can't happen" error.
Only a basic logic bug in a _bt_insertonpg() caller could lead to a
violation of this invariant (index corruption won't do it). A "can't
happen" error seems inappropriate (it is arbitrary at best).
Demote the error to a simple assertion. This matches similar nearby
sanity checks.
