WdfSpinlockRelease rule (kmdf)

The WdfSpinlockRelease rule specifies that calls to WdfSpinLockAcquire and WdfSpinlockRelease are used in a balanced way within a KMDF event callback function. When the KMDF event callback function returns, the driver should not hold the framework spin lock object that was obtained by a previous call to WdfSpinLockAcquire.
