VMScsiController: Adds an extra adapter

[a73xsh]

Every time when I launch DSC in VM added new SCSI adapter.
The adapter should not be added if it already exists

Here is my code.

Node $NodeName
 {

        xVHD "Disk-$VHDXName" {

                Name             = $VHDXName
                Path             = $Path
                Generation       = $Generation
                MaximumSizeBytes = $MaximumSizeBytes
                Ensure           = $Ensure

            }

        xVMScsiController "Controller-$SCSIControllerNumber" {

            Ensure           = $Ensure
            VMName           = $VMName
            ControllerNumber = 0
            RestartIfNeeded  = $true
            DependsOn          = "[xVHD]Disk-$VHDXName"

        }
            # Attach the VHD
        xVMHardDiskDrive "ExtraDisk-$VHDXName" {
                VMName             = $VMName
                Path               = (Join-Path "$Path" -ChildPath "$VHDXName")
                ControllerType     = 'SCSI'
                ControllerNumber   = 0
                ControllerLocation = 1
                Ensure             = $Ensure
                DependsOn          = "[xVMScsiController]Controller-$SCSIControllerNumber"
            }

    }

This log shows that the adapter number 3 has been added.
