Re: [PATCH v3] Bluetooth: L2CAP: Fix not tracking outstanding TX ident

I had trouble connecting my Bluetooth headphones on Linux 7.0-rc1,
and a bisect landed me on this commit 6c3ea155e5ee. A revert fixes it.

The symptom is that when connecting the headphones via bluetoothctl,
it either hangs or appears (in pavucontrol) as if it's using the AAC
codec, but there's no output. Sometimes after some time, it disconnects
and then re-connects successfully but using the MSBC/CVSD codecs.

I haven't had time to troubleshoot this further so far, mainly posting
if it can save someone a bisect.
