dm: core: Fix uclass_probe_all to really probe all devices
uclass_probe_all uses uclass_first_device/uclass_next_device assigning
the return value.
The interface for getting meaningful error is
uclass_first_device_check/uclass_next_device_check, use it.
Also do not stop iteration when an error is encountered. Probing all
devices includes those that happen to be after a failing device in the
uclass order.
Fixes: a59153dfeb ("dm: core: add function uclass_probe_all() to probe all devices")
