[PATCH] drm: virtio: replace reference/unreference with get/put

[Aastha Gupta]

DRM core uses reference/unreference suffixes for refcounting
functions, but kernel uses get/put (e.g. kref_get/put()).
Replace reference/unreference with get/put for consistency
and also it's shorter.

The following cocci script was used to generate the patch:

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);
)
