Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_dpp.c: In function dpp_get_optimal_number_of_taps:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_dpp.c:137:11: warning: variable pixel_width set but not used [-Wunused-but-set-variable]

It is never used and can be remove.
