dm: treewide: Use uclass_next_device_err when accessing second device

There are a couple users of uclass_next_device return value that get the
first device by other means and use uclass_next_device assuming the
following device in the uclass is related to the first one.

Use uclass_next_device_err because the return value from
uclass_next_device will be removed in a later patch.
