drm_exec_prepare_obj() and drm_exec_prepare_array() both reserve
dma-fence slots and hence a dma_resv_list without ever freeing it.

Make sure to call drm_gem_private_object_fini() for each GEM object
passed to drm_exec_prepare_obj()/drm_exec_prepare_array() throughout the
test to fix this up.

While at it, remove some trailing empty lines.
