dedup: Fix #7033 device not initialized when using legacy config format

- the default dedupengine had no driver_type and was not initialized as
  a Legacy or Dedup2 dedupengine
- When no Dedupengine is specified in a Device resource and if there is
  only one dedupengine specified in the Storage resource or in a
  Dedupengine resource then use this one. Else return an error.
