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.
