igb: change the head and tail offsets into pointers
Since we are writting to the head/tail pointers frequently we might as well
save ourselves some processing time by converting the head and tail offsets
directly to pointers. This will shave a few cycles off the rx/tx path and
allows us to move one step closer to the rings being a bit more independant of
each other.
