bcachefs: kill bch_backpointer.bucket_offset usage
bch_backpointer.bucket_offset is going away - it's no longer needed
since we no longer store backpointers in alloc keys, the same
information is in the key position itself.
And we'll be reclaiming the space in bch_backpointer for the bucket
generation number.
