[libvirt] [PATCH v2 2/5] uml: Fix umlInotifyEvent dom object handling

[John Ferlan]

The virDomainObjListFindByName will return a locked and reffed
object. If we call virDomainObjListRemove that will unlock the
object upon return, thus we need to relock the object before
making the call to virDomainObjEndAPI.
