When processing hci_cb entries we want first registered callbacks to be
called first and later ones later. This is because eventually the L2CAP
callbacks that are part of the core will use this list and get
registered first. To keep the same order of calling L2CAP callbacks
before e.g. RFCOMM the order of elements needs to be this way.
