Sean Christopherson 090cd45b21 KVM: selftests: Clean up requirements for XFD-aware XSAVE features
Provide informative error messages for the various checks related to
requesting access to XSAVE features that are buried behind XSAVE Feature
Disabling (XFD).

Opportunistically rename the helper to have "require" in the name so that
it's somewhat obvious that the helper may skip the test.
