KVM: nSVM: Directly (re)calc vmcb02 intercepts from nested_vmcb02_prepare_control()

Now that nested_vmcb02_recalc_intercepts() provides guardrails against it
being incorrectly called without vmcb02 active, invoke it directly from
nested_vmcb02_recalc_intercepts() instead of bouncing through
svm_mark_intercepts_dirty(), which unnecessarily marks vmcb01 as dirty.
