Sanlock patch accepted

My sanlock patch has been accepted by the libvirt maintainers today.  It will be included in libvirt 0.10.0.  It fixes the problem where all sanlock resources are released when hot-dettaching a disk from a qemu/kvm domain, leaving the other (disk) resources unlocked/unprotected.

Meanwhile, this is a situation that can be recovered from through the sanlock client by re-registering the assigned disks, or by avoiding the problem altogether by applying the patch.
