[0/2] uvcvideo: require spec compliance to avoid bugs

Message

Some syzkaller reproducers have triggered cases where the devices would not
comply with the UVC specification and warnings would result.

These cases can be simply fixed by preventing the allocation of entities
with duplicate IDs or zero IDs.

  media: uvcvideo: require entities to have a unique ID
  media: uvcvideo: require entities to have a non-zero ID
