Subject: [PATCH Review 1/1] drm/amdgpu: fix disable ras feature failed when unload drvier v2
v2:
still need call ras_disable_all_featrures to handle
ras initilization failure case.
Function amdgpu_device_fini_hw is called before amdgpu_device_fini_sw, so ras ta will unload before send ras disable command, ras dsiable operation must before hw fini.
