[PATCH] drm: Convert prime dma-buf <-> handle to rhashtable

Currently we use a linear walk to lookup a handle and return a dma-buf, and vice versa. A long overdue TODO task is to convert that to a hashtable. Since the initial implementation of dma-buf/prime, we now have resizeable hashtables we can use (and now a future task is to RCU enable the lookup!).
