Zhang Rui 89935315f1 PNP / ACPI: proper handling of ACPI IO/Memory resource parsing failures
Before commit b355cee88e (ACPI / resources: ignore invalid ACPI
device resources), if acpi_dev_resource_memory()/acpi_dev_resource_io()
returns false, it means the the resource is not a memeory/IO resource.

But after commit b355cee88e, those functions return false if the
given memory/IO resource entry is invalid (the length of the resource
is zero).

This breaks pnpacpi_allocated_resource(), because it now recognizes
the invalid memory/io resources as resources of unknown type.  Thus
users see confusing warning messages on machines with zero length
ACPI memory/IO resources.

Fix the problem by rearranging pnpacpi_allocated_resource() so that
it calls acpi_dev_resource_memory() for memory type and IO type
resources only, respectively.

Fixes: b355cee88e (ACPI / resources: ignore invalid ACPI device resources)
