[libvirt] [PATCH] xm_internal.c: remove dead store and associated leak

[Jim Meyering]

This one took a little thinking.

I'm not 100% sure that the comment in my log is sufficient
justification for removing the virGetDomain call.  If we leave it,
we'll have to free it and remove the XXX comment.

Subject: [PATCH] xm_internal.c: remove dead store and associated leak

* src/xm_internal.c (xenXMDomainDefineXML): Dead store to "olddomain" --
and comment ;-) highlighted that the virGetDomain call represented a
leak.  It was also useless, seeing as how preceding call to
virHashLookup(priv->nameConfigMap found def->name.
