    Bluetooth: Fix to show internet access as marked when pan is connected

    isPrefered is always true for PAN. So internet access menu checkbox
    is always marked on. Marking internet access menu checkbox based on
    pan connection status should solve this issue.

    Bluetooth: Fix to connect PANU from the internet access menu

    isPrefered is always true for PAN. So PANU connect fails,
    Once user clicks on the internet access menu in Profiles
    Setting. As PAN is not auto connect profile, So PANU should
    connect from the internet access menu in Profiles Setting.

    Bluetooth: Set isPreferred to true for PanProfile Connections.

    isPreferred is always true for PAN profile so that DUT can
    initiate connection with remote device. Curretnly we are
    returning true only when pan profile is in connected, so
    it will return false when pan profile is not connected and
    will never initiate connection on click.
