KVM: VMX: fix use after free of vmx->loaded_vmcs
commit 26a865f4aa8e66a6d94958de7656f7f1b03c6c56 upstream.
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.
