i2c: designware: convert to dev_err_probe() on request IRQ error

Simplify the error handling of devm_request_irq() in
i2c_dw_probe_master() and i2c_dw_probe_slave() by converting to:

return dev_err_probe();

instead of calling:

dev_err();
return ret;

This also handle deferred probe error without spamming the log.
