PCI: rzg3s: Propagate platform_get_irq_byname() errors
platform_get_irq_byname() may return specific error codes such as
-EPROBE_DEFER, but rzg3s_pcie_init_irqdomain() replaces all failures
with -EINVAL.
This breaks probe deferral by preventing the driver core from retrying
probe once the interrupt provider becomes available.
Propagate the original error code instead.
