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.
