tests/qtest: device-plug-test: Reverse the usage of double/single quotes

The usage of double/single quotes in test_pci_unplug_json_request()
should be reversed to work on both win32 and non-win32 platforms:

- The value of -device parameter needs to be surrounded by "" as
  Windows does not drop '' when passing it to QEMU which causes
  QEMU command line option parser failure.
- The JSON key/value pairs need to be surrounded by '' to make the
  JSON parser happy on Windows.
