make sure the very first fragment triggers an rx_callback

On the first session server, the first payload packet gets queued
but the Rx callback will only be invoked when the second packet
is received.

By initializing enqueue_epoch in the session, we can make sure that
the RX callback will be invoked for the first packet as well.
