drm/amdgpu: Report individual reset error

If reinitialization of one of the GPUs fails after reset, it logs
failure on all subsequent GPUs eventhough they have resumed
successfully.

A sample log where only device at 0000:95:00.0 had a failure -

	amdgpu 0000:15:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:65:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:75:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:85:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:95:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:e5:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:f5:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:05:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:15:00.0: amdgpu: GPU reset end with ret = -5

To avoid confusion, report the error for each device
separately and return the first error as the overall result.
