[libvirt] [PATCH] xen: Avoid double free of virDomainDef in xenDaemonCreateXML

Beside dumpxml still being broken with the xen driver (hint [1] ;) )
there is also a quite annoying problem of creating new definitions
now failing. Using virt-manager this even disrupts the connection
to the host and the guest is not created persistent although
it does come up.

Subject: [PATCH] xen: Avoid double free of virDomainDef in xenDaemonCreateXML

The virDomainDef is allocated by the caller and also used after
calling to xenDaemonCreateXML. So it must not get freed by the
callee.
