Dmitry Baryshkov 50883f733c drm/msm/dpu: replace IS_ERR_OR_NULL with IS_ERR during DSC init
Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover dpu_hw_dsc_init() can not return NULL.
Replace the IS_ERR_OR_NULL() call with IS_ERR().

This follows the commit 740828c73a ("drm/msm/dpu: fix error handling
in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but
then the commit f2803ee91a ("drm/msm/disp/dpu1: Add DSC support in
RM") added it for DSC init.
