rtc: max77686: Properly handle regmap_irq_get_virq() error code
commit fb166ba1d7f0a662f7332f4ff660a0d6f4d76915 upstream.
The regmap_irq_get_virq() can return 0 or -EINVAL in error conditions
but driver checked only for value of 0.
This could lead to a cast of -EINVAL to an unsigned int used as a
interrupt number for devm_request_threaded_irq(). Although this is not
yet fatal (devm_request_threaded_irq() will just fail with -EINVAL) but
might be a misleading when diagnosing errors.
