libceph: Fix NULL pointer dereference in auth client code
commit 2cb33cac622afde897aa02d3dcd9fbba8bae839e upstream.
A malicious monitor can craft an auth reply message that could cause a
NULL function pointer dereference in the client's kernel.
To prevent this, the auth_none protocol handler needs an empty
ceph_auth_client_ops->build_request() function.
