    Remove warning about a loop parsing evbuffer socks
    
    This behavior is normal when we want more data than the evbuffer
    actually has for us.  We'll ask for (say) 7 bytes, get only 5
    (because that's all there is), try to parse the 5 bytes, and get
    told "no, I want 7".  One option would be to bail out early whenever
    want_length is > buflen, but sometimes we use an over-large
    want_length.  So instead, let's just remove the warning here: it's
    not a bug after all.
