qemu: domain: Don't call namespace setup for storage already accessed by vm When doing block commit we need to allow write for members of the backing chain so that we can commit the data into them. qemuDomainDiskChainElementPrepare was used for this which since commit 786d8d91b4 calls qemuDomainNamespaceSetupDisk which has very adverse side-effects, namely it relabels the nodes to the same label it has in the main namespace. This was messing up permissions for the commit operation since its touching various parts of a single backing chain. Since we are are actually not introducing new images at that point add a flag for qemuDomainDiskChainElementPrepare which will refrain from calling to the namespace setup function. Calls from qemuDomainSnapshotCreateSingleDiskActive and qemuDomainBlockCopyCommon do introduce new members all calls from qemuDomainBlockCommit do not, so the calls are anotated accordingly.
