Subject: [PATCH] alloc-track: error out when auto-remove is not set

Since replacing the node now happens in the stream job, where the
option cannot be read from (it's internal to the driver), it will
always be treated as on.

qemu-server will always set it, make sure to have other users notice
the change (should they even exist). The option can be fully dropped
in the future while adding a version guard in qemu-server.
