Subject[PATCH v2] drm/amdgpu: off by on in amdgpu_device_attr_create_groups() error handling
This loop in the error handling code should start a "i - 1" and end at
"i == 0". Currently it starts a "i" and ends at "i == 1". The result
is that it removes one attribute that wasn't created yet, and leaks the
zeroeth attribute.

Fixes: 4e01847c38f7 ("drm/amdgpu: optimize amdgpu device attribute code")
