error with inout args

Problem outlined here: http://groups.google.com/group/peachfuzz/browse_thread/thread/b02ea0d0e19ae3a. If you comment out the if paramflags lines it seems to be resolved. Looks like a problem with the _cominterface_meta's _fix_inout_args. When calling something that takes an inout, you'll get a stack trace like this:

``` python
