[PATCH v2 2/4] KVM: selftests: Move __vm_xsave_require_permission() below CPUID helpers

[Sean Christopherson]

Move __vm_xsave_require_permission() below the CPUID helpers so that a
future change can reference the cached result of KVM_GET_SUPPORTED_CPUID
while keeping the definition of the variable close to its intended user,
kvm_get_supported_cpuid().

No functional change intended.
