dragonball: Allow question_mark warning in allocate_device_resources()

As the rust toolchain version bump to its 1.66.0 release raised a
warning about the code being able to be refactored to use `?`.

For now that's something we don't need to change, so let's ignore such
warning in this very specific case.
