Alex Elder c734b79655 rbd: don't print warning if not mapping a parent ... The presence of the LAYERING bit in an rbd image's feature mask does not guarantee the image actually has a parent image. Currently that bit is set only when a clone (i.e., image with a parent) is created, but it is (currently) not cleared if that clone gets flattened back into a "normal" image. A "parent_id" query will leave the parent_spec for the image being mapped a null pointer, but will not return an error. Currently, whenever an image with the LAYERED feature gets mapped, a warning about the use of layered images gets printed. But we don't want to do this for a flattened image, so print the warning only if we find there is a parent spec after the probe.
