[PATCH 35/42] KVM: selftests: Drop unnecessary use of kvm_get_supported_cpuid_index()

[Sean Christopherson]

Use kvm_get_supported_cpuid_entry() instead of
kvm_get_supported_cpuid_index() when passing in '0' for the index, which
just so happens to be the case in all remaining users of
kvm_get_supported_cpuid_index() except kvm_get_supported_cpuid_entry().

Keep the helper as there may be users in the future, and it's not doing
any harm.
