xen/pci: Use 'acpi_gsi_to_irq' value unconditionally.
In the past we would only use the function's value if the returned value was not equal to 'acpi_sci_override_gsi'. Meaning that the INT_SRV_OVR values for global and source irq were different. But it is OK to use the function's value even when the global and source irq are the same. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
