Bluetooth: iso: Fix circular lock in iso_listen_bis
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: iso: Fix circular lock in iso_listen_bis This fixes the circular locking dependency warning below, by releasing the socket lock before enterning iso_listen_bis, to avoid any potential deadlock with hdev lock.
