e1000: Count CRC in Tx statistics

The Software Developer's Manual 13.7.4.5 "Packets Transmitted (64 Bytes)
Count" says:
> This register counts the number of packets transmitted that are
> exactly 64 bytes (from <Destination Address> through <CRC>,
> inclusively) in length.

It also says similar for the other Tx statistics registers. Add the
number of bytes for CRC to those registers.

(Mjt: pick this for 7.2 too: a fix by its own and makes next patch to apply cleanly)
