igb: use buffer_info->dma instead of shinfo->nr_frags to determine unmap
This change makes it so that we use buffer_info->dma instead of
shinfo->nr_frags to determine if we need to unmap a received skb. By doing
this we can avoid a cache miss on small packets since the buffer_info
structure should already be prefetched.
