drm/ttm/tests: Fix a warning in ttm_bo_unreserve_bulk

Browse Source 
BOs in a bulk move have to share the same reservation object. That is
not the case in the ttm_bo_unreserve_bulk subtest. Update
ttm_bo_kunit_init() helper to accept dma_resv object so we can define
buffer objects that share the same resv. Update calls to that helper
accordingly.
