Previously, calling bch2_btree_has_scanned_nodes() when btree node scan hadn't actually run would erroniously return false - causing us to think a btree was entirely gone. This fixes a 6.16 regression from moving the scheduling of btree node scan out of bch2_btree_lost_data() (fixing the bug where we'd schedule it persistently in the superblock) and only scheduling it when check_toploogy() is asking for scanned btree nodes.
