media: i2c: vgxy61: Check return value of devm_gpiod_get_optional() in vgxy61_probe()

The devm_gpiod_get_optional() function may return an error pointer
(ERR_PTR) in case of a genuine failure during GPIO acquisition,
not just NULL which indicates the legitimate absence of an optional
GPIO.

Add an IS_ERR() check after the function call to catch such errors and
propagate them to the probe function, ensuring the driver fails to load
safely rather than proceeding with an invalid pointer.
