35a1e2ad17 i40e: Cleanup Tx buffer info layout
- drop the mapped_as_page u8 from the Tx buffer info as it was unused
- use the DMA unmap accessors for Tx DMA
- replace checks of DMA with checks of the unmap length to verify if an
  unmap is needed
- update the Tx buffer layout to make it consistent with igb, ixgbe

c304fdac6c i40e: Drop unused completed stat
The Tx "completed" stat was part of the original rewrite for detecting
Tx hangs.  However some time ago in ixgbe I determined that we could
just use the packets stat instead.  Since then this stat was
removed from ixgbe and it serves no purpose in i40e so it can be
dropped.
