Error: variable 'kw' referenced before assignment

[Arati Mahimane]

When wsme receives a request with a payload containing some unknown fields it results in a Client side Unknown argument error.
If funcdef.ignore_extra_args is set to true, it results in the following error:

        UnboundLocalError: local variable 'kw' referenced before assignment

The error comes from https://github.com/stackforge/wsme/blob/master/wsme/rest/args.py#L236

Code snippet:
    try:
        kw = dataformat.parse(
            body, datatypes, bodyarg=funcdef.body_type is not None
        )
    except UnknownArgument:
        if not funcdef.ignore_extra_args:
            raise

    return (), kw

Solution:

This can be fixed by initializing the kw variable.
