[PATCH v5 02/16] drm/msm/dpu: fix error condition in dpu_encoder_virt_atomic_mode_set

[Dmitry Baryshkov]

The commit b954fa6baaca ("drm/msm/dpu: Refactor rm iterator") removed
zero-init of the hw_ctl array, but didn't change the error condition,
that checked for hw_ctl[i] being NULL. Use indices check instead.
