drm/msm/dpu: Add missing NULL pointer check for pingpong interface

Browse Source 
commit 88733a0b64872357e5ecd82b7488121503cb9cc6 upstream.

It is checked almost always in dpu_encoder_phys_wb_setup_ctl(), but in a
single place the check is missing.
Also use convenient locals instead of phys_enc->* where available.
