// IncrementIoCount and DecrementIoCount
//
// DESCRIPTION
//
// We keep a pending IO count. This count is initialized to one.
// Subsequently, the count is incremented for each new IRP received or
// created and is decremented when each IRP is completed.
// Transition to 'one' therefore indicates no IO is pending and signals
// Adapter->RemoveEvent. Transition to 'zero' signals an event
// (Adapter->RemoveEvent) to enable device removal.
//
// INPUT
//
// Adapter Ptr to the adapter object
//
// OUTPUT
//
// -
