> After each rebuild driver deallocates q_vectors, so the interrupt throttle rate
> (ITR) settings get lost.
> 
> Create a function to save and restore ITR for each queue. If a user increases
> the number of queues, restore all the previous queue settings for each
> existing queue, and the additional queues will get the default setting.
