Update multipart.asciidoc

Browse source 
For reading a multipart message where the part is a file :-
 
this line below leads to a badmap error after the last chunk has been read. So the functionality isn't affected but it just throws an error at the very end.
            `Req = case cow_multipart:form_data(Headers) of`
           
Removing the pattern matching and replacing it with just
            `case cow_multipart:form_data(Headers) of`
           
resolves the issue. Doing this means the recursive call `multipart(Req)` should be replaced with `multipart(Req1)`.
