drm/i915: Rename struct intel_ringbuffer to struct intel_ring

Browse Source 
The state stored in this struct is not only the information about the
buffer object, but the ring used to communicate with the hardware. Using
buffer here is overly specific and, for me at least, conflates with the
notion of buffer objects themselves.
