agp/hp: fail gracefully if we don't find an IOC

Bail out if we don't find an enclosing IOC.  Previously, if we didn't
find one, we tried to set things up using garbage for the SBA/IOC register
address, which causes a crash.

This crash only happens if firmware supplies a defective ACPI namespace, so
it doesn't fix any problems in the field.
