Subject: [PATCH v2 net-next 1/5] l2tp: fix switch default error handling in l2tp_nl_cmd_session_create()

Although this issue is harmless since that code path is protected by the
check on l2tp_nl_cmd_ops[]/l2tp_nl_cmd_ops[]->session_create(), fix error
handling for L2TP_PWTYPE_IP/default case in l2tp_nl_cmd_session_create()
