[PATCH linux-next] drm/i915/display: Remove unused variable in the for loop.

[luo penghao]

Variable is not used in the loop, and its assignment is redundant too.
So it should be deleted.

The clang_analyzer complains as follows:

drivers/gpu/drm/i915/display/intel_fb.c:1018:3 warning:

Value stored to 'cpp' is never read.
