[PATCH v2 0/6] improve AP queue reset processing

[Tony Krowiak]

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.
 
Change log v1 => v2:
-------------------
Remove patch 7/7 to restore original behavior since we don't know whether
interrupts are disabled when an unexpected response code is returned from 
ZAPQ. (Halil)
