[libvirt] [PATCH 02/10] rbd: drop support for ceph 0.94
Commit 21deeaf02fdf216b08210fc899579736973ca81d added a stub
for volStorageBackendRBDGetFlags without marking the arguments
as unused, thus breaking the build.
Now that we require diff_iterate2 to be present, remove all the
conditionally compiled code, including the stub function.
