[PATCH] drm/amd: Fix amdgpu_device_find_parent()

[Mario Limonciello]

commit e4300be450453 ("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.

Fixes: e4300be450453 ("drm/amd: Add dedicated helper for 
amdgpu_device_find_parent()")
