c96b56d by Dario Lombardo (lomato@xxxxxxxxx):

    frame: fix crash when dissectors add the maximum number of tree items.
    
    When underlying dissectors exceed MAX_TREE_ITEMS, the frame dissector
    will fail when adding more items. We make room for the following items
    by decrementing the count for the current tree before adding them.
    
    This change will fix all errors where underlying dissectors add MAX_TREE_ITEMS
    items to the tree.
