session: set fifo's session index before vcl attach
Current implementation may have timing issue:
1. The TCP 3-way-handshake is completed but the app is busy and
does not process the CONNECTED event.
2. VPP receive some data from peer and try to send a RX event to
VCL, but the fifo's client session index is not initialized yet.
So this event will be sent to incorrect session 0.
Type: fix
