[Intel-gfx] [PATCH 3/3] drm/i915: Simplify error handling in intel_modeset_all_pipes()

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

No need for the extra break statements and whatnot, just return the
error directly. And tighten the scope of the local variables while at
it.
