rbd: rename rbd_device->id
The "id" field of an rbd device structure represents the unique client-local device id mapped to the underlying rbd image. Each rbd image will have another id--the image id--and each snapshot has its own id as well. The simple name "id" no longer conveys the information one might like to have. Rename the device "id" field in struct rbd_dev to be "dev_id" to make it a little more obvious what we're dealing with without having to think more about context.
