drm/msm/dpu: Fix memory leak in msm_mdss_parse_data_bus_icc_path

[ Upstream commit e283e61bc28a20e2dbc60a8fbb8bb6622be70ac5 ]

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.
Defer getting path1 to fix this.
