iproute: TYPE keyword is not optional, fix help text accordingly
This is a bit pedantic, but brackets ([]) show optional values and since
TYPE must not become empty, they're not suited to surround the type
keyword choices. Use curly braces instead.
Also add some missing whitespace to the parameter list above.
