acpi,srat: Fix incorrect device handle check for Generic Initiator 

The Generic Initiator Affinity Structure in SRAT table uses device
handle type field to indicate the device type. According to ACPI
specification, the device handle type value of 1 represents PCI device,
not 0.

Fixes: 894c26a1c2 ("ACPI: Support Generic Initiator only domains")
