[1/1] Bluetooth: ISO: Fix master BIS cleanup

Commit Message

Iulia Tanasescu Aug. 30, 2023, 3:38 p.m. UTC

This fixes the master BIS cleanup procedure - as opposed to CIS cleanup,
no HCI disconnect command should be issued. A master BIS should only be
terminated by disabling periodic and extended advertising, and terminatings
the BIG.
