    cxgbe: fix enabling lro & rxtimestamps
    
    A recent change caused iq flags, like LRO, to be set before
    init_iq(). However, init_iq() clears those flags, so they
    became effectively impossible to set.   This change moves
    the initializion of these flags to after the call to init_iq().
    This fixes LRO.
