xen/pci: Move check for acpi_sci_override_gsi to xen_setup_acpi_sci.
Previously we would check for acpi_sci_override_gsi == gsi every time
a PCI device was enabled. That works during early bootup, but later
on it could lead to triggering unnecessarily the acpi_gsi_to_irq(..) lookup.
The reason is that acpi_sci_override_gsi was declared in __initdata and
after early bootup could contain bogus values.
This patch moves the check for acpi_sci_override_gsi to the
site where the ACPI SCI is preset.
