[libvirt] [PATCH 23/38] qemu: domain: Process only one object in qemuDomainPrepareDiskSourceTLS

[Peter Krempa]

Remove the loop from qemuDomainPrepareDiskSourceTLS and rename it to
qemuDomainPrepareStorageSourceTLS. Currently there is no backing chain
to prepare so fixing one device is equivalent. In the future it will be
reused in a function which will do the looping.
