[ethtool] ethtool: Correct register dump offsets for Intel 82575 chipsets.

From: Matthew Vick <matthew.vick@intel.com>

When support was added to dump the registers on 82575 chipset devices,
six register offsets (receive/transmit desc length, head, and tail)
were incorrectly mapped. This patch remaps the offsets to the correct
registers.

The status is 'arrived just as I went on vacation, and forgotten'.

I'll be sure to apply this before releasing ethtool 3.2.
