Allow DSM segments to be created as pinned
dsm_create and dsm_attach assumed that a current resource owner was
always in place. Exploration with the API show that this is
inconvenient: sometimes one must create a dummy resowner, create/attach
the DSM, only to pin the mapping later, which is wasteful. Change
create/attach so that if there is no current resowner, the dsm is
effectively pinned right from the start.
