[libvirt] [PATCH] storage: fix omitted slash in gluster volume URI

[Eric Blake]

When doing 'virsh vol-dumpxml' on a gluster pool's volume, the
resulting URI incorrectly omitted a slash between hostname and
path:  gluster://192.168.122.206rhsvol1/fedora-19.img

This is fallout from me rebasing earlier versions of my patch,
I had originally played with always requiring the gluster volume
to have a leading slash, but it was easier to use the gluster
API if the gluster volume name was guaranteed to have no slash;
while I got the URI of the pool correct, I forgot to fix the URI
of a libvirt volume.

* src/storage/storage_backend_gluster.c
(virStorageBackendGlusterRefreshVol): Use correct starting point
since uri construction requires leading slash.

Once approved, I'm also pushing to v1.2.0-maint
