CLOUDSTACK-5661 [VMware] DetachIsoCmd succeeds even though cdrom is locked by 
VM as cdrom is mounted

DetachISO is succeeding even though detach opeartion is failing as cdrom is 
locked by VM as it was mounted inside VM.
Detect if cdrom is locked or not. If locked fail detach operation and warn user 
to unmount before detaching the iso/cdrom device.
