usb: dwc3: google: Remove redundant dev_err()

The platform_get_irq_byname() function already prints an error message
internally upon failure using dev_err_probe(). Therefore, the explicit
dev_err() is redundant and results in duplicate error logs.

Remove the redundant dev_err() call to clean up the error path.
