    Bluetooth: ISO: Fix getname not returning broadcast fields

    getname shall return iso_bc fields for both BIS_LINK and PA_LINK since
    the likes of bluetoothd do use the getpeername to retrieve the SID both
    when enumerating the broadcasters and when synchronizing.

    Fixes: a7bcffc ("Bluetooth: Add PA_LINK to distinguish BIG sync and PA sync connections")
