Commit f29861aa301c5 ("PCI: xilinx: Switch to
msi_create_parent_irq_domain()") changed xilinx_pcie::msi_domain from child
devices' interrupt domain into Xilinx AXI bridge's interrupt domain.
However, xilinx_pcie_intr_handler() wasn't changed and still reads Xilinx
AXI bridge's interrupt domain from xilinx_pcie::msi_domain->parent. This
pointer is NULL now.
Update xilinx_pcie_intr_handler() to read the correct interrupt domain
pointer.
