    host: Wake up stalled conns when a conn is dropped
    
    When a connection is dropped, it may free up some ACL packet capacity in
    the controller.  When this happens, we need to wake up all stalled
    connections.
    
    We want to wake up connections every time the ACL data buffer capcity
    increases (whenever `ble_hs_hci_add_avail_pkts()` is called).
