drm/panel: ltk050h3146w: only print message when GPIO getting is not EPROBE_DEFER

Browse source

devm_gpiod_get_optional may return EPROBE_DEFER in case the GPIO
controller isn't yet probed when the panel driver is being probed.

In that case, a spurious and confusing error message about not being
able to get the reset GPIO is printed even though later on the device
actually manages to get probed.

Use dev_err_probe instead so that the message is only printed when it
truly matters.
