ixgbe: drop ring->head, make ring->tail a pointer instead of offset
This change drops ring->head since it is not used in any hot-path and can
easily be determined using IXGBE_[RT]DH(ring->reg_idx).
It also changes ring->tail into a true pointer so we can avoid unnecessary
pointer math to find the location of the tail.
In addition I also dropped the setting of head and tail in
ixgbe_clean_[rx|tx]_ring. The only location that should be setting the head
and tail values is ixgbe_configure_[rx|tx]_ring and that is only while the
queue is disabled.
