05d249352f drm/exec: Pass in initial # of objects 
In cases where the # is known ahead of time, it is silly to do the table
resize dance.

806fd6d005 drm/test: drm_exec: fix memory leak on object prepare 
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.

991eb531f4 drm/exec: add test case for using a drm_exec multiple times 
Not really a common use case, but let's make sure that we don't
accidentially break that somehow.

drm/tests: Alloc drm_device on drm_exec tests 
The drm_exec tests where crashing[0] because of a null dereference. This
is caused by a new access of the `driver` attribute of `struct
drm_driver` on drm_gem_private_object_init(). Alloc the drm_device to
fix that.
