[Intel-gfx] [PATCH] drm/i915: Propagate invalid setcrtc cloning errors back to userspace

[Matt Roper]

When invalid cloning configurations were detected during modeset, we
never copied the error code into the return value variable, leading us
to return 0 (success) to userspace.

Testcase: igt/kms_setmode
