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

Bluetooth: ISO: ensure no dangling hcon references in iso_conn

After iso_conn_del(), ISO sockets should not dereference the hcon any
more. Currently, clearing iso_conn::hcon relies on iso_conn_del()
releasing the last reference to the iso_conn.

Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to
avoid more complex reasoning on races about who holds the last
reference.
