c9b6e94963 drm/i915: Ditch the i915_gem_ww_ctx loop member 
It's only used by the for_i915_gem_ww() macro and we can use
the (typically) on-stack _err variable in its place.

v2:
- Don't clear the _err variable when entering the loop
  (Matthew Auld, Maarten Lankhorst).
- Use parentheses around the _err macro argument.
- Fix up comment.
