interface_sort_filter_model: don't dereference a NULL pointer
This fixes a crash in InterfaceSortFilterModel::mapToSource().
sourceModel was set to match the sourceModel of the underlying
InterfaceFrame. When Wireshark is closed,
InterfaceSortFilterModel::mapToSource() is called after
InterfaceFrame was freed, the sourceModel is NULL in this case.
