The proper way to avoid calling on_deinit() callback on an already
deinitialized volume is to deinitialize type callbacks, as it is done
in the previous commit.
This reverts commit a7f70687a9.

After moving from a volume, it's priv is assigned to the new owner.
Destroying the volume after moving from it must not attempt to use the
priv, especially not to attempt to deinit member volumes in case of
composite volume.
