i2c: mux: reg: don't log an error for probe deferral
It's possible that i2c_mux_reg_probe_dt() could return -EPROBE_DEFER. In that case, driver will request a probe deferral and an error suggesting device tree parsing problem will be reported. This is a pretty confusing information. Let's change the error handling, so driver will be able to request probe deferral without logging not related errors.
