Subject: drm/amdgpu: Fix memory leaks at amdgpu_init() error path
Git-commit: c60e22f7199b5fe7cee4007ccb3b27bb8a506476
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

amdgpu driver checks vgacon_text_force() after some initializations
but without cleaning up.  This will result in leaks.

Move the check of vgacon_text_force() to the beginning of
amdgpu_init() for fixing it and also for optimization.
