libxl: Properly cleanup after libxlDomObjFromDomain

Browse Source 
Commit id '9ac945078' altered libxlDomObjFromDomain to return
a locked *and* ref counted object for some specific purposes;
however, it neglected to alter all the consumers of the helper
to use virDomainObjEndAPI thus leaving many objects with extra
ref counts.
