Set new domain configs to contain at least 1 vCPU add a check that
maximum vCPU count isn't set to 0 and remove unnecesary checks.
The openvz test suite change is necessary since the test case generates
the config via virDomainDefNew but does not set the vCPU info. With the
change to virDomainDefNew the expected output has changed.
