drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup
The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback
in case of YUV output") introduced a smatch warning about another
conditional block in dpu_encoder_helper_phys_cleanup() which had assumed
hw_pp will always be valid which may not necessarily be true.
Lets fix the other conditional block by making sure hw_pp is valid
before dereferencing it.
