Previously it used dr_entity_sense for this, which works for physical DRCs. However, for logical DRCs, it didn't cover the case where a logical DRC has a drc->dev but the state is LOGICAL_UNUSABLE (e.g. a hotplugged CPU before CAS). In this case, the dr_entity_sense of this DRC returns UNUSABLE and the code was considering that there were no dev attached, making spapr_drc_need= ed return 'false' when in fact we would like to migrate the DRC. Changing it to check for drc->dev instead works for all DRC types.
