ixgbevf: Drop use of eitr_low and eitr_high for hard coded values
This patch drops the use of eitr_low and eitr_high as values being stored in the adapter structure. Since the values have no external way to be changed they might as well just be hard coded values and save us the space on the adapter structure.
