/****
@func       DWORD | ApiFixNotifyCb | If a cluster component wants to make
            a fixup to the cluster registry as a part of form/join it
            must register with the NM via this API.

@parm       IN PVOID| pContext | A pointer to the context information passed
            to NmRegisterFixupCb().

@parm       IN PVOID *ppPropertyList |

@parm       IN PVOID pdwProperyListSize | A pointer to DWORD where the size
            of the property list structure is returned.


@comm       For NT 5.0, the api layer performs the fixup for the security
            descriptor.  If the new security descriptor entry for the cluster
            is not present in the registry , convert the old format to the new
            one and write it to the cluster registry.

@rdesc      Returns a result code. ERROR_SUCCESS on success.
