> Currently in ice_get_tx_pending we try to read a Tx ring's tail. This is then
> compared with the software based head (next_to_clean) to determine if we
> have pending work. This will never work because reading of the Tx ring's tail
> is no longer supported. Fix this by using the software based tail
> (next_to_use) to determine if there is pending work.
