[PATCH 4/5] spapr: Pass &error_abort when getting some PC DIMM properties

[Greg Kurz]

Both PC_DIMM_SLOT_PROP and PC_DIMM_ADDR_PROP are defined in the
default property list of the PC DIMM device class:

    DEFINE_PROP_UINT64(PC_DIMM_ADDR_PROP, PCDIMMDevice, addr, 0),

    DEFINE_PROP_INT32(PC_DIMM_SLOT_PROP, PCDIMMDevice, slot,
                      PC_DIMM_UNASSIGNED_SLOT),

They should thus be always gettable for both PC DIMMs and NVDIMMs.
An error in getting them can only be the result of a programming
error. It doesn't make much sense to propagate the error in this
case. Abort instead.
