Previous commit added support for active RBD disk snapshots,
using the same qmp_transaction used also for external snapshots.
The same transaction can be used to mix internal and external snapshots.
To allow this, this commit simply removes the check that disallows mixing
for active snapshots.
Note that previous commits added validation disallowing deletion
and reverting of RBD disks. The same validation applies to the mixed
type of snapshots introduced by this commit.
