VMDvdDrive: Get-VMIdeController fails on Gen 2 VM

[iainbrighton]

When attempting to attach an ISO to Generation 2 VM, it fails when calling Get-VMIdeController with the following error:

Get-VMIdeController : Generation 2 virtual machines do not support IDE.

Adding -ErrorAction SilentlyContinue to the Get-VMIdeController call in the Test-ParameterValid method does appear to resolve the problem.
