powerpc/pseries: Improve error code on reconfiguration notifier failure
Reconfiguration notifier call for device node may fail by several reasons,
but it always assumes kmalloc failures.
This enables reconfiguration notifier call chain to get the actual error
code rather than -ENOMEM by converting all reconfiguration notifier calls
to return encapsulate error code with notifier_from_errno().
