[PATCH RFC 07/40] qemu: domain: Tolerate NULL @disk in qemuDomainPrepareDiskSourceData

[Peter Krempa <pkrempa@xxxxxxxxxx>]

In some cases we want to prepare a @src which is not meant to belong to
a disk and thus does not require us to copy the data. Allow passing in
NULL @disk into qemuDomainPrepareDiskSourceData.
