Subject: Bluetooth: use memset avoid memory leaks

Patch-mainline: v6.0-rc1

Git-commit: a5133fe87ed827ce94084eecb7830a6d451ef55c

References: jsc#PED-1407

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
