rapidio/rionet: fix multicast packet transmit logic

commit 7c4a6106d6451fc03c491e61df37c044505d843a upstream.

Fix multicast packet transmit logic to account for repetitive transmission
of single skb:
- correct check for available buffers (this bug may produce NULL pointer
  crash dump in case of heavy traffic);
- update skb user count (incorrect user counter causes a warning dump from
  net_tx_action routine during multicast transfers in systems with three or
  more rionet participants).
