For most cases the ixgbevf driver will only ever contain a single Tx and
single Rx queue.  In order to track that it makes more sense to use a
pointer instead of using a bitmap which must be search in order to locate
the ring on an adapter index.  As such I am changing the code to use
pointers and an iterator to access all rings on a given q_vector.
