[IA64] Fix wrong assumption in acpi_gsi_to_irq
The ia64's acpi_gsi_to_irq() function assumes irq == vector. But in fact irq can be different from vector. This patch fix this wrong assumption. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
