[libvirt] [PATCH v7 11/13] qemu: Forbid blocks operations with quorum

[Matthias Gatto]

For now we block all blocks operations with RAID disks.

Quorum doesn't support BlockRebase neither, but
qemuDomainBlockRebase call qemuDomainBlockPullCommon or
qemuDomainBlockCopyCommon which are alerady blocked.
