KVM: nSVM: WARN and abort vmcb02 intercepts recalc if vmcb02 isn't active
WARN and bail early from nested_vmcb02_recalc_intercepts() if vmcb02 isn't
the active/current VMCB, as recalculating intercepts for vmcb01 using logic
intended for merging vmcb12 and vmcb01 intercepts can yield unexpected and
unwanted results.
In addition to hardening against general bugs, this will provide additional
safeguards "if" nested_vmcb02_recalc_intercepts() is invoked directly from
nested_vmcb02_prepare_control().
