WdfWaitlock rule (kmdf)

The WdfWaitlock rule specifies that calls to WdfWaitLockAcquire are used in strict alternation with WdfWaitlockRelease. 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 WdfWaitLockAcquire.
