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

[ Upstream commit 7c3643f204edf1c5edb12b36b34838683ee5f8dc ]

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.
