Jesse Brandeburg a68de58d27 i40e: fix race in hang check
The driver was having some issues with false Tx hang detection. This
makes the driver a little more direct with the checks for progress
forward by directly checking the head write back address and tail register
when determining progress.  This avoids Tx hangs where the software
gets behind, because we are directly checking hardware state when
determining hang state.
