I rather not add anything to hci_request.h since we want to deprecate
its functions, in fact we might as well try to start removing the code
paths that attempt to access things like
disconnected_accept_list_entries since I think most of the code is
already in place in hci_sync.c things like __hci_req_update_scan if it
is no longer used anywhere else.
