Similar to what was done for em in r220254, this patch improves the error handling in lem when a TSO packet has too many segments to DMA. This improves the behavior when either call to bus_dmamap_load_mbuf_sg() returns ENOMEM. Although we don't need to go back and redo any offload calculation in lem, doing it this way reduces code duplication.
Comments welcome. -Andrew
