[ Upstream commit a5133fe87ed827ce94084eecb7830a6d451ef55c ]
Similar to the handling of l2cap_ecred_connect in commit d3715b2333e9 ("Bluetooth: use memset avoid memory leaks"), we thought a patch might be needed here as well.
Use memset to initialize structs to prevent memory leaks in l2cap_le_connect
