drm/msm/dpu: Remove set but unused variables

We get warning:

In function ‘dpu_encoder_virt_enable’: drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c:1145:33:
warning: variable ‘priv’ set but not used [-Wunused-but-set-variable]
 1145 |         struct msm_drm_private *priv;

In function ‘dpu_encoder_virt_disable’: drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c:1182:33:
warning: variable ‘priv’ set but not used [-Wunused-but-set-variable]
 1182 |         struct msm_drm_private *priv;

Remove these unused but set variables
