> e1000e_put_txbuf() can be called from normal reclamation path as well as
> when a DMA mapping failure, so we need to differentiate these two cases
> when freeing SKBs to be drop monitor friendly. e1000e_tx_hwtstamp_work()
> and e1000_remove() are processing TX timestamped SKBs and those should
> not be accounted as drops either.

> - differentiate normal reclamation from TX DMA fragment mapping errors
> - removed a few invalid dev_kfree_skb() replacements (those are already
> drop monitor friendly)
