Drivers may want to avoid requiring CAP_NET_ADMIN for subsequent
drm-ras operations. However, userspace must still be able to access
the list of RAS nodes to determine the node IDs. So, drop the
CAP_NET_ADMIN requirement for dumping RAS nodes so that drivers
with different permission requirements are still able to use the
interface.
Additionally, initialize the return value to zero in
drm_ras_nl_list_nodes_dumpit to avoid leaking uninitialized kernel
memory (especailly now that this function no longer requires admin
permissions).
This prepares the interface to be used for telemetry by the qaic
driver.
