Historically the snapshot code attempted to forbid internal snapshots
with UEFI both in active and inactive case. Unfortunately due to the
intricacies of UEFI probing this didn't really work for inactive VMs
which made users rely on the feature.

Now with the changes to store detected UEFI environment also in the
inactive definition this broke the feature for those users.

Since the varstore doesn't really change that much in the lifecycle of a
VM it usually is okay to simply leave it as is.

Restore the functionality for inactive snapshots by disabling the check.

In the future when uefi snapshotting will be added the rest of the
condition will also be removed.
