[libvirt] [PATCH 07/17] qemu: Introduce qemuDomainDeviceDefValidateControllerIDE

[John Ferlan]

From: Lin Ma <lma at suse.com>

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.
