[PATCH 3/5] drm: Rename dev_priv_size to buf_priv_size

[Damien Lespiau <damien.lespiau@intel.com>]

This field is really the size of the per-driver private data attached to
a struct drm_buf. Name it accordingly and add a comment so it doesn't
get confused with, say, the size of the private data attatched to a struct
drm_device.
