libxl: fix parse_backend_path and device_backend_path to be mutual

Currently if libxl__parse_backend_path is used and then you try to get
the original path again with libxl__device_backend_path the
result is wrong. This patch fixes the issue, so transformation from
path to libxl__device and back is reciprocal.
