Replace drm_gem_object_reference/unreference function with *_get/put()
suffixes, because it is shorter and consistent with the kernel
kref_get/put() functions. The following Coccinelle script was used:

@@
expression e;
@@

(
-drm_gem_object_reference(e);
+drm_gem_object_get(e);
|
-drm_gem_object_unreference(e);
+drm_gem_object_put(e);
|
-drm_gem_object_unreference_unlocked(e);
+drm_gem_object_put_unlocked(e);
)
