staging: comedi: add a kref to comedi device Add a `struct kref refcount` member to `struct comedi_device` to allow safe destruction of the comedi device. Only free the comedi device via the 'release' callback `kref_put()`. Currently, nothing calls `kref_put()`, so the safe destruction is ineffective, but this will be addressed by later patches.
