igb: remove unecessary q_vector declarations and remove itr_shift
This change removes the use of itr_shift since a mac type call can be
used just as easily to identify the only HW that needs to have the itr
shifted.
In addition it removes two unecessary declarations of a q_vector
pointer from the initialization path.
