Bluetooth: hci_sync: Fix broadcast/PA when using an existing instance

When using and existing adv_info instance for broadcast source it
needs to be updated to periodic first before it can be reused, also in
case the existing instance already have data hci_set_adv_instance_data
cannot be used directly since it would overwrite the existing data so
this reappend the original data after the Broadcast ID, if one was
generated.

Example:

bluetoothctl># Add PBP to EA so it can be later referenced as the BIS ID
bluetoothctl> advertise.service 0x1856 0x00 0x00
bluetoothctl> advertise on
...
< HCI Command: LE Set Extended Advertising Data (0x08|0x0037) plen 13
        Handle: 0x01
        Operation: Complete extended advertising data (0x03)
        Fragment preference: Minimize fragmentation (0x01)
        Data length: 0x09
        Service Data: Public Broadcast Announcement (0x1856)
          Data[2]: 0000
        Flags: 0x06
          LE General Discoverable Mode
          BR/EDR Not Supported
...
bluetoothctl># Attempt to acquire Broadcast Source transport
bluetoothctl>transport.acquire /org/bluez/hci0/pac_bcast0/fd0
...
< HCI Command: LE Set Extended Advertising Data (0x08|0x0037) plen 255
        Handle: 0x01
        Operation: Complete extended advertising data (0x03)
        Fragment preference: Minimize fragmentation (0x01)
        Data length: 0x0e
        Service Data: Broadcast Audio Announcement (0x1852)
        Broadcast ID: 11371620 (0xad8464)
        Service Data: Public Broadcast Announcement (0x1856)
          Data[2]: 0000
        Flags: 0x06
