lsm: Prevent removing auto-gen snapshot if VM powered off during LSM

If the VM is powered off during LSM, removing the auto-generated
snapshot will end up by a cold merge operation. Until BZ 1246114 is
fixed, cold merge copies data from base volume to top and removes the
base volume. This behavior isn't desired during LSM hence, it is
prevented in this patch.
Once BZ 1246114 is fixed, this limit can be removed.
This behavior is tracked by BZ 1369942.
