Title: Inverting the hash of driver_mac_addresses returned by machine.provider....

...capability(:nic_mac_addresses).

The previous code expected the hash to use the mac addresses as the keys, the original code had the indices as the keys. This prevented VagrantPlugins::GuestWindows::Cap::ConfigureNetworks::create_vm_interface from matching the mac addresses supplied by the VM to the mac addresses supplied by GuestNetwork::network_adapters.
