[PATCH 3/4] drm/i915: Rename local struct intel_ringbuffer variables

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Majority of the code calls these ringbuf so fix up a few
places which use something else to be consistent.

Coccinelle script of:

@@
expression E;
identifier r;
