rust: pci: impl Send + Sync for pci::Device 



Commit 7b948a2a ("rust: pci: fix unrestricted &mut pci::Device")
changed the definition of pci::Device and discarded the implicitly
derived Send and Sync traits.

This isn't required by upstream code yet, and hence did not cause any
issues. However, it is relied on by upcoming drivers, hence add it back
in.
