sdp: Fix bad handling of small rcvbuf size in zcopy

- Do not send RdmaRdComp when no buffers
- Same for SendSm
- post at least 3 buffers in RX to have the minimal number of credits
- make purge_tx_ring ignore WR used by RDMA
- fixed a typo, to reschedule tx_cq_poll timer according to tx queue and
  not to rx queue (!)
- Allow credit updates when less than half RX Q is filled
