[PATCH 3/5] drm/msm: Fix IS_ERR_OR_NULL() vs NULL check in msm_icc_get()

[Gaosheng Cui]

The of_icc_get() function returns NULL or error pointers on error path,
so we should use IS_ERR_OR_NULL() to check the return value.

Fixes: 5ccdcecaf8f7 ("drm/msm: lookup the ICC paths in both mdp5/dpu and mdss devices")
