ceph: messenger: reduce args to create_authorizer

Make use of the new ceph_auth_handshake structure in order to reduce
the number of arguments passed to the create_authorizor method in
ceph_auth_client_ops.  Use a local variable of that type as a
shorthand in the get_authorizer method definitions.
