KVM: selftests: Make get_supported_cpuid() returns "const"
Tag the returned CPUID pointers from kvm_get_supported_cpuid(), kvm_get_supported_hv_cpuid(), and vcpu_get_supported_hv_cpuid() "const" to prevent reintroducing the broken pattern of modifying the static "cpuid" variable used by kvm_get_supported_cpuid() to cache the results of KVM_GET_SUPPORTED_CPUID. Update downstream consumers as needed. Signed-off-by: Sean Christopherson <seanjc@google.com> Link: https://lore.kernel.org/r/20220614200707.3315957-31-seanjc@google.com
