b1021e7b39 cmd_migrate: Make fsck after migrate-superblock debug-only 
There is no reason to run a fsck there for common use, as the FS is now
modified only by calling consistency-preserving APIs.

Also switch the debug-only fsck to nochanges mode for easier debugging.

020763ad66 cmd_migrate: Reimplement cmd_migrate_superblock 
Now the FS is first started RW, then new superblock is written and metadata updated.
This ensures that all recovery/upgrades/downgrades are performed at the beginning.

bcachefs uses 64 bit inode numbers by default, which overflow genradix
keys when we multiply the inode number by the object size for the actual
genradix lookup.

Switch to a rhashtable, and only index files that actually have
hardlinks.
