drm/msm: remove variable set but not used

The code that uses variable mdss has been removed, So the declaration and assignment of the variable can be removed.

Eliminate the following clang warning:
drivers/gpu/drm/msm/msm_drv.c:513:19: warning: variable 'mdss' set but not used [-Wunused-but-set-variable]

Reported-by Abaci Robot <[email protected]>

Fixes 2027e5b3413d ("drm/msm: Initialize MDSS irq domain at probe time")
