x86/cpuid: fix raw FEATURESET_7d0 reporting

Commit 62b1879693 ("x86: further CPUID handling adjustments") added
FEATURESET_7d0 reporting but forgot to update calculate_raw_featureset()
function. As result, the value reported by xen-cpuid contains 0.

Fix that by properly filling raw_featureset[FEATURESET_7d0].
