CVE-2026-74541

Bluetooth: ISO: clear iso_data always when detaching conn from hcon

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: ISO: clear iso_data always when detaching conn from hcon

When setting conn->hcon = NULL, also conn->hcon->iso_data = NULL is
necessary, otherwise later iso_conn_free() will UAF.

Fix clearing of iso_data in iso_sock_disconn()

Fixes KASAN: slab-use-after-free in iso_conn_hold_unless_zero on
iso_sock_release() followed by hci_abort_conn_sync().
