[PATCH next] drm/msm/dpu: Fix uninitialized variable in dpu_crtc_kickoff_clone_mode()

[Dan Carpenter]

After the loop there is a check for whether "wb_encoder" has been set
to non-NULL, however it was never set to NULL.  Initialize it to NULL.

Fixes: ad06972d5365 ("drm/msm/dpu: Reorder encoder kickoff for CWB")
