From: Guchun Chen <guchun.chen@xxxxxxx> [ Upstream commit 067f44c8b4590c3f24d21a037578a478590f2175 ] In amdgpu_fence_driver_hw_fini, no need to call drm_sched_fini to stop scheduler in s3 test, otherwise, fence related failure will arrive after resume. To fix this and for a better clean up, move drm_sched_fini from fence_hw_fini to fence_sw_fini, as it's part of driver shutdown, and should never be called in hw_fini. v2: rename amdgpu_fence_driver_init to amdgpu_fence_driver_sw_init, to keep sw_init and sw_fini paired.
