rust: pci: use `Option<&IdInfo>` for device ID info

It is possible that `pci_device_id_any` will be passed to the driver, e.g.
`driver_override` is used on the device. Therefore, the driver must be able
to handle the case where `driver_data` is 0. Thus, update the `probe`
functions to get `Option`.

The current code cannot tell if the info does not exist or is the first
entry; however this will be achievable once the code is updated to use a
`&'static IdInfo` pointer instead of indices.
