Currently, when using blockdev-add to add a drive, qemu can not insert
this new drive to QemuOptsList. So this will cause the bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1088176
This patch check the ID is duplicate or not firstly, then if not, insert
the new drive with this ID to QemuOptsList.
