KVM: VMX: fix use after free of vmx->loaded_vmcs
After free_loaded_vmcs executes, the "loaded_vmcs" structure is kfreed, and now vmx->loaded_vmcs points to a kfreed area. Subsequent free_loaded_vmcs then attempts to manipulate vmx->loaded_vmcs. Switch the order to avoid the problem. https://bugzilla.redhat.com/show_bug.cgi?id=1047892 Reviewed-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
