[Freedreno] [PATCH] drm/msm/dpu: don't access mode pointer before it is set

[Dmitry Baryshkov]

Move the initializer for the mode variable to the declaration point to
remove unitialized variable access from the DEBUG_DPU macro. This fixes
the following warning:

drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c:250:37: note: initialize the variable 'mode' to silence this warning

Fixes: d7d0e73f7de3 ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback")
