[PATCH] drm/msm/dpu: Fix memory leak in msm_mdss_parse_data_bus_icc_path

[Miaoqian Lin]

of_icc_get() alloc resources for path1, we should release it when not
need anymore. Early return when IS_ERR_OR_NULL(path0) may leak path1.
Add icc_put(path1) in the error path to fix this.

Fixes: b9364eed9232 ("drm/msm/dpu: Move min BW request and full BW disable back to mdss")
