Use dev_err_probe() to simplify the error path and unify a message template.

Using this helper is totally fine even if err is known to never be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.
