[ros-kernel] bug in class2 ?

[Hartmut B. <har...@te...>]

The call to IoCompletRequest from atapi doesn't free the virtual address 
space and the memory from the mdl within the irp. Normaly 
IoSecondStageCompletion does call IoReadWriteCompletion for read/write 
requests and IoReadWriteCompletion does the job. ScsiClassBuildRequest sets 
the function within the irp to IRP_MJ_SCSI and IoReadWriteCompletion is 
never called. I have added the necessary code to ScsiClassIoComplete, but 
I'm not sure, if this is the right position. There is also a wrong call to 
IoMarkIrpPending in ScsiClassReadWrite.
