drm/amd: Fix amdgpu_device_find_parent()
commit eb53125a7ad9 ("drm/amd: Add dedicated helper for
amdgpu_device_find_parent()") created a dedicated helper to find
the parent device outside of the dGPU but it had a logic error
that caused it to walk all the way up the topology and return
the wrong device.
Break out of the loop when the device is found.
