bcachefs: btree_gc can now handle unknown btrees (2024-06-29 16:57:24 -0400)

---------------------------------------------------------------- bcachefs fixes for 6.9 stable

Downgrade path fixes; this fixes downgrade recovery passes not running when downgrading from on disk format version 1.9; this results in missing allocation information and writes immediately hanging due to the allocator thinking there are no free buckets.
