libxl: rename a field in libxl__domain_create_state

The libxl__stub_dm_spawn_state field in libxl__domain_create_state was
named dmss. That was inconsistent with how things were named (usually
acronym) and there was already libxl__dm_spawn_state named dmss in other
places.

Change dmss to sdss and fix up all sites that reference this field.  No
functional change.
