Fix build error when CONFIG_ACPI is not set/enabled:

../arch/x86/pci/xen.c: In function ‘pci_xen_init’:
../arch/x86/pci/xen.c:410:2: error: implicit declaration of function ‘acpi_noirq_set’; did you mean ‘acpi_irq_get’? [-Werror=implicit-function-declaration]
  acpi_noirq_set();

Fixes: 88e9ca161c13 ("xen/pci: Use acpi_noirq_set() helper to avoid #ifdef")
