bcachefs: version_upgrade is now an enum
The version_upgrade parameter is now an enum, not a bool, and it's
persistent in the superblock:
- compatible (default): upgrade to the latest compatible version
- incompatible: upgrade to latest incompatible version
- none
Currently all upgrades are incompatible upgrades, but the next release
will introduce major:minor versions.
