drm/msm/dpu: Reapply CTM if modeset is needed

Browse Source 
Add a !drm_atomic_crtc_needs_modeset() check to
_dpu_crtc_setup_cp_blocks() so that CTM is reapplied if the LM/DSPP
blocks were reallocated during modeset or after a suspend/resume.

Changes in V2:
- Fixed commit message

Changes in V3:
- Added mention of suspend/resume case back to commit message
