powerpc: Check rc of notifier chain for memory remove
The return code from invocation of the notifier for pSeries_reconfig_chain during update of the device tree is not checked. This causes writes to /proc/ppc64/ofdt to update memory properties (i.e. ibm,dyamic-reconfiguration-memory) to always return success, instead of the result of the notifier chain. This happens specifically when we remove/add memory from the device tree on machines using memory specified in the ibm,dynamic-reconfiguration-memory property of the device tree.
