hwrng: xgene - Simplify using dev_err_probe()

dev_err_probe simplifies the idiom:

if (ret != -EPROBE_DEFER)
dev_err(...)
return ret;

, emits the error code in a human readable way and even yields a useful
entry in /sys/kernel/debug/devices_deferred in the EPROBE_DEFER case.

So simplify and at the same time improve the driver by using
dev_err_probe().
