Subject: Altix: more ACPI PRT support
From: John Keller <[EMAIL PROTECTED]>

The SN Altix platform does not conform to the IOSAPIC IRQ routing model. 
Add code in acpi_unregister_gsi() to check if (acpi_irq_model ==
ACPI_IRQ_MODEL_PLATFORM) and return.

Due to an oversight, this code was not added previously when
similar code was added to acpi_register_gsi().
