[XEN PATCH v3 06/16] x86/nestedhvm: switch to using_{svm,vmx} check

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

Use using_{svm,vmx} instead of cpu_has_{svm,vmx} that not only checks if CPU
supports corresponding virtialization technology, but also if it is
supported by build configuration.

This fixes build when VMX=n or SVM=n, because then start_nested_{svm,vmx}
routine(s) not available.
