Since sysupgrade creates the provisioning volume by default, it takes the
lowest free volume ID before the kernel and rootfs volumes are created.
This shifts their IDs by one, so devices that hardcode the rootfs volume
in root= (e.g. root=/dev/ubiblock0_1) no longer boot after a sysupgrade.
Create the provisioning volume with the last volume ID instead.
A provisioning volume that already exists at a low ID is kept and has to
be removed by hand.
