tcp: Probe net.core.{r,w}mem_max, don't set SO_{RCV,SND}BUF if low
If net.core.rmem_max and net.core.wmem_max sysctls have low values,
we can get bigger buffers by not trying to set them high -- the
kernel would lock their values to what we get.
Try, instead, to get bigger buffers by queueing as much as possible,
and if maximum values in tcp_wmem and tcp_rmem are bigger than this,
that will work.
While at it, drop QUICKACK option for non-spliced sockets, I set
that earlier by mistake.
