Remove obsolete _bt_insert_parent() comment.

Remove a comment that refers to a coding practice that was fully removed
by commit a8b8f4db, which introduced MarkBufferDirty().  It looks like
the comment was even obsolete before then, since it concerns
write-ordering dependencies with synchronous buffer writes.
