[libvirt] [PATCH 1/2] daemon: virtlogd: Drop the server shortcut ref pointer

[Erik Skultety]

We put the server into a hash table as we do with the other daemons,
there is no compelling reason why it should have another pointer
dedicated just to the server. Besides, the locking daemon doesn't have
it and virtlogd is essentially a copy paste of virtlockd.
