[libvirt] [PATCH 07/10] util: Initialize virResctrlInfo struct right away

[Martin Kletzander]

There is no need to have virResctrlGetInfo() when it must be called after
virResctrlInfoNew() anyway, otherwise it's just an unusable object.  When we
wrap the logic inside the New() function we'll save some calls later as well.
