    enic: fix last packet not being sent
    
    The last packet of the tx burst function array was not being
    emitted until the subsequent call.  The nic descriptor index
    was being set to the current tx descriptor instead of one past
    the descriptor as required by the nic.
    
    Fixes: d739ba4c6abf ("enic: improve Tx packet rate")
