Commit 18f6290a6a ("hw/intc: GICv3 ITS initial framework")
incremented version_id and minimum_version_id fields of
VMStateDescription vmstate_its. This breaks the migration between
6.2 and 6.1 with the following message:

qemu-system-aarch64: savevm: unsupported version 1 for 'arm_gicv3_its' v0
qemu-system-aarch64: load of migration failed: Invalid argument

Revert that change.

Oops, I didn't notice that the version bump lines were still
in the patchset I applied :-(

No problem. I did not notice either ;-)
