[libvirt] [PATCH] Release only specific sanlock resource

[Frido Roose]

This is a patch for bug 826704
All sanlock resources get released when hot-dettaching a disk from the domain
because virLockManagerSanlockRelease uses the wrong function parameters/flags.
With the patch only the resources that should be released are cleaned up.
