Remove unnessary assertIsNotNone

If volume['id'] is None, wait_for_volume_status will fail, so
there is no need to check whether volume['id'] is None after
wait_for_volume_status.

Besides, name_field and descrip_field are only used in one function,
so it is no need to define them in resource_setup as instance
variables.
