uclass_first_device might return NULL for the device despite a zero
return code. Currently, this might lead to null pointer dereferencing,
since the returned device is not properly checked.
We switch to uclass_first_device_err to make sure that the returned device is
valid.

v2:

Use uclass_first_device_err instead of explicit null checking
