    Bluetooth: hci_sync: Fix scan state after PA Sync has been established

    Passive scanning is used to program the address of the peer to be
    synchronized, so once HCI_EV_LE_PA_SYNC_ESTABLISHED is received it
    needs to be updated after clearing HCI_PA_SYNC then call
    hci_update_passive_scan_sync to return it to its original state.
