[libvirt PATCH 1/6] Use g_auto for virURI almost everywhere

[Ján Tomko <jtomko@xxxxxxxxxx>]

Convert all the cases where we can unconditionally free
the virURI at the end of scope.

In libxlDomainMigrationDstPrepare, uri is only filled
if uri_in was present, so moving the virURIFree out of
the condition is safe.
