StorPortSpinLock rule (storport)

This rule verifies that locks that are acquired via StorPortAcquireSpinLock are promptly released via StorPortReleaseSpinLock. The miniport driver fails the rule if it attempts to acquire a lock that it had already acquired, or if it attempts to release a lock that it had not acquired. In addition, at the end of the dispatch or cancel routine, the driver should not hold any spin locks.
