Fix DetachedInstanceError for VolumeAttachment
Patch I253123d5451b32f0e3143916e41aaa1af75561c2 fixed the
DetachedInstanceError for VolumeAttachment OVOs but only partially, as
apparently it was dependent on the SQLAlchemy version due to the use os
"hasattr".
This patch replaces "hasattr" with a check on the object's dictionary,
which will never trigger a Lazy Load.
