[libvirt] [PATCH 09/17] conf: put subsys part of virDomainHostdevDef into its own struct
To shorten some new code that accesses the many fields within the
subsys struct of a hostdev, create a separate toplevel, typedefed
virDomainHostdevSubsys struct so that we can define temporary pointers
to the subsys part.
