WDK 6001: PREfast bug

Here is it. KeReleaseSpinLock was added temporarily to try to get rid of
PREfast warning. Unfortunately, this does not help, and a valid sequence of 2
MS's functions causes a warning:

// !!!
713 KeReleaseSpinLock(&(Disk->SpinLock), Irql);
714 IoCompleteRequest(Irp, IO_NO_INCREMENT);

vsnap.c(714) : warning 28192: No resource of the class 'SpinLock'
can be held when this function is called. 'Disk->SpinLock' is currently held.
