gpio: msic: fix error return code in platform_msic_gpio_probe()
platform_get_irq() returns an error code, but the gpio-msic driver
ignores it and always returns -EINVAL. This is not correct, and
prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.
