[PATCH v2 07/15] qemu: Introduce qemuDomainDeviceDefValidateControllerIDE

[John Ferlan <jferlan@xxxxxxxxxx>]

From: Lin Ma <lma@xxxxxxxx>

Move the IDE controller check from command line building to
controller def validation.

Cause the IDE case for command line building to generate a
failure if called to add an IDE since that shouldn't happen
if the Validate code did the right thing.
