KVM: VMX: Switch __vmx_exit() and kvm_x86_vendor_exit() in vmx_exit()

KVM: VMX: Switch __vmx_exit() and kvm_x86_vendor_exit() in vmx_exit()

In the vmx_init() error handling path, the __vmx_exit() is done before
kvm_x86_vendor_exit().  They should follow the same order in vmx_exit().

But currently __vmx_exit() is done after kvm_x86_vendor_exit() in
vmx_exit().  Switch the order of them to fix.
