TS-1708: Using tr-pass port option causes requests with large headers to hang

If 4KB of headers are read and we haven't decided on requets validity yet, disregard
tr-pass option in order to avoid blocking the writer

> When tr-pass is enabled and a request comes in on a new connection with total size of request headers > 4K it will hang in the parser (and never time out).
> In order to support tr-pass, we clone the ua_buffer_reader, but until the parser decides the request is valid/invalid, we do not consume data from the clone. Eventually, the underlying iobuffer fills up and the parser won't be called with the rest of the pending data.
