qemu: process: Fix alias for disk-tray-moved event

Currently we'd report the alias of the drive which is backing the cdrom
rather than the device itself:

 $ virsh event ds tray-change --loop
 event 'tray-change' for domain ds disk drive-ide0-0-1: opened
 event 'tray-change' for domain ds disk drive-ide0-0-1: closed

Report the disk device alias as we document in the API docs:
