libceph: store ceph_auth_handshake pointer in ceph_connection
We already copy authorizer_reply_buf and authorizer_reply_buf_len into ceph_connection. Factoring out __prepare_write_connect() requires two more: authorizer_buf and authorizer_buf_len. Store the pointer to the handshake in con->auth rather than piling on. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Sage Weil <sage@redhat.com>
