    migration: fix memory leak in qmp_migrate_set_parameters
    
    "tmp.tls_hostname" and "tmp.tls_creds" allocated by 
migrate_params_test_apply()
    is forgot to free at the end of qmp_migrate_set_parameters(). Fix that.
    
    The leak stack:
    Direct leak of 2 byte(s) in 2 object(s) allocated from:
