GW RPC-HTTP - Don't drop 4 byte stub from the pipe 

* Though not frequent, it's possible to get TsProxySetupReceivePipe
  data of stublength 4 that is actual data.  This happens when
  header->common.call_id == rpc->PipeCallId &&
  !(header->common.pfc_flags & PFC_LAST_FRAG).
  This should address GW disconnects that manifest as SSL read errors.
