x86/pci: Create PCI/MSI irqdomain after x86_init.pci.arch_init()
Invoking x86_init.irqs.create_pci_msi_domain() before
x86_init.pci.arch_init() breaks XEN PV.
The XEN_PV specific pci.arch_init() function overrides the default
create_pci_msi_domain() which is obviously too late.
As a consequence the XEN PV PCI/MSI allocation goes through the native
path which runs out of vectors and causes malfunction.
Invoke it after x86_init.pci.arch_init().
Fixes: 6b15ffa07dc3 ("x86/irq: Initialize PCI/MSI domain at PCI init time")
