liblp: Force 10.0 metadata on downgrade to Q.
Q liblp only supports 10.0 super partition metadata, so
forcefully downgrade the current metadata version too.
On retrofit Virtual A/B devices, the metadata version is
at most 10.1, because the new VIRTUAL_AB flag is not set
on retrofit devices.
In version 10.1, two per-partition flags: UPDATED and DISABLED
are introduced.
- The updated flag is set when the device undergoes a Virtual A/B
update before. Clear it.
- The disabled flag should only be set on metadata files used by
libfiemap ImageManager. It shouldn't be used on super partition metadata.
Hence, this CL should only clear UPDATED flag.
