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.
Fixes: 894c26a1c274 ("ACPI: Support Generic Initiator only domains")
