KVM: nVMX: Make setup/unsetup under the same conditions

Browse Source 
Make sure nested_vmx_hardware_setup/unsetup() are called in pairs under
the same conditions.  Calling nested_vmx_hardware_unsetup() when nested
is false "works" right now because it only calls free_page() on zero-
initialized pointers, but it's possible that more code will be added to
nested_vmx_hardware_unsetup() in the future.
