ixgbe: change vector numbering so that queues end up on correct CPUs

This changes the numbering scheme slightly. Previously the ordering was
coming out like this:
Rx-2
Rx-1
Rx-0
TxRx-0
Which would drop two queues on CPU 0. This change makes it so that the
ordering is like this:
Rx-3
Rx-2
Rx-1
TxRx-0
This means that each CPU will have it's own Rx queue, and only CPU 0 will
have the Tx queue.
