    Fix filtering on IP heuristic subdissectors.

    The IP dissector passes 'tree' to its heuristic dissectors instead
    of the 'parent_tree' passed to the normally registered dissectors.
    These two are generally the same except that 'tree' is set to NULL
    in cases where IP is not referenced - a local optimization that
    should not be passed down to the lower layers. The result is that
    the filter:
    ip && PROTO matches
    but:
    PROTO does not match.

    This changes the two types of dissectors to behave the same by
    getting 'parent_tree'.
