[PATCH] PCI: pcie-rcar: Fix OF node passed to MSI irq domain

[Phil Edworthy]

The OF node passed to irq_domain_add_linear() should be a
pointer to interrupt controller's device tree node, or NULL,
but not the PCI controller's node.

This fixes an oops in msi_domain_alloc_irqs() when it tries
to call msi_check().
