Remove unnecessary wait_for_volume_resource_status
Remove unnecessary wait_for_volume_resource_status

In test_volume_crud_with_volume_type_and_extra_specs,
wait_for_volume_resource_status is already included in
self.create_volume, so there is no need to call it after
self.create_volume. This is to remove it for code clean.
