[PATCH v5 08/11] drm/i915: two small moves towards more consistency

[Dave Gordon <david.s.gordon@intel.com>]

From: Nick Hoath <nicholas.hoath@intel.com>

Rename i915_gem_cleanup_ringbuffer() to i915_gem_cleanup_engines(),
to relect what it actually does (clean up all the engines, not a
single ringbuffer). The name is probably a legacy from the days
when there was only one "ring" (i.e. engine) and one ringbuffer!

While we're looking at this function, there's a strangely-formatted
comment block that looks ugly, so let's prettify it.
