Subject: drm/amd/pp: Remove dead error checking code on Vega10
Git-commit: d246cd53fd6a6bffc9e4dcf045d8031f445353fb
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
when smu failed, print out the error info immediately
for debug. smum_send_msg_to_smu always return true,
so no need to check return value.
