This series introduces several improvements to the function that performs
AP queue resets:

* Breaks up reset processing into multiple smaller, more concise functions.

* Use TAPQ to verify completion of a reset in progress rather than mulitple
   invocations of ZAPQ.

* Check TAPQ response codes when verifying successful completion of ZAPQ.

* Fix erroneous handling of some error response codes.

* Increase the maximum amount of time to wait for successful completion of
   ZAPQ.

* Always clean up IRQ resources when the ZAPQ response code indicates an
   error.

* Consider reset complete when ZAPQ response code indicates the adapter to
   which a queue is connected is deconfigured. All queues associated with an
   adapter are reset when it is deconfigured.

This series largely matches what I've already reviewed. I like the way you broke this up, it does a better job telling the story.

Here's my R-b for the entire series.
