rust: devres: fix doctest build under !CONFIG_PCI

Browse Source 
The doctest requires `CONFIG_PCI`:

    error[E0432]: unresolved import `kernel::pci`
        --> rust/doctests_kernel_generated.rs:2689:44
         |
    2689 | use kernel::{device::Core, devres::Devres, pci};
         |                                            ^^^ no `pci` in the root
         |
    note: found an item that was configured out
        --> rust/kernel/lib.rs:96:9
    note: the item is gated here
        --> rust/kernel/lib.rs:95:1

Thus conditionally compile it (which still checks the syntax).
