This patch fixes the following issues in the existing scenario schema
assertions:
1. The assertion that ensures the existence of pCPU affinity in all
pre- and post-launched VMs does not count the pCPU settings under a
VM properly.
2. The assertion that ensures the presence of CAT settings of a defined
VM is no longer needed as it was originally designed to capture
configurator issues.
