[PATCH 08/12] qemuMonitorAddObject: Refactor cleanup

[Peter Krempa]

Remove freeing/clearing of @props as the function doesn't guarantee that
it happens on success, rename the variable hodling copy of the alias and
use g_autofree to automatically free it and remove the cleanup label as
well as 'ret' variable.
