pps: clients: gpio: Propagate return value from pps_gpio_probe
If the pps-gpio driver was probed prior to the GPIO device it uses, the
devm_gpiod_get call returned an -EPROBE_DEFER error, but pps_gpio_probe
replaced that error code with -EINVAL, causing the pps-gpio probe to
fail and not be retried later. Propagate the error return value so that
deferred probe works properly.
