ACPI / PCI / hotplug: Avoid warning when _ADR not present
acpiphp_enumerate_slots() walks ACPI namenamespace under
a PCI host bridge with callback register_slot().
register_slot() evaluates _ADR for all the device objects
and emits a warning message for any error. Some platforms
have _HID device objects (such as HPET and IPMI), which
trigger unnecessary warning messages.
This patch avoids emitting a warning message when a target
device object does not have _ADR.
