Re: [libvirt] [PATCH] qemu_monitor: search memballoon QOM device path using alias

Commit 4a585a88 introduced searching QOM device path by alias, let's use it for memballoon too. This may speedup the search because in most cases we will find the correct QOM device path directly by using alias without the need for the recursion code.
