I've changed the check to something like this:
diff --git a/net/bluetooth/l2cap_core.c b/net/bluetooth/l2cap_core.c
index ebff14c..f88b9c8 100644
--- a/net/bluetooth/l2cap_core.c

- if ((bt_sk(sk)->defer_setup && sk->sk_state != BT_CONNECT2) ||
- (!bt_sk(sk)->defer_setup && sk->sk_state != BT_CONFIG)) {

rej.reason = cpu_to_le16(0x0002);
Seems to work fine.
