allow empty data_extra_pool in zone placement
RGWZoneParams::get_head_data_pool() and rgw_get_obj_data_pool() both use placement.data_extra_pool directly instead of calling placement.get_data_extra_pool(), which will return data_pool if extra_data_pool is empty.

The master commit changes a line in the function "rgw_get_obj_data_pool" which was added by 9c1b828e838. That commit is not in jewel, and it's quite complicated, so it's unclear how to do this backport in a minimal way.
