Ensure that failures are fatal for upgrade_check

Ansible's fail will fail only current host in case of met conditions
while continuing play for others.

In order to prevent further execution for all hosts in case of unmet
conditions, which may further break the cluster, `any_errors_fatal`
was added to fail tasks.

This will end the play for current batch and cancel further batches.
