[Intel-gfx] [PATCH] drm/i915/selftests: Break out of the lrc layout test after register mismatch

[Chris Wilson]

AFter detecting a register mismatch between the protocontext and the
image generated by HW, immediately break out of the double loop.
(Otherwise we end up a second configuing error message.)
