The call to 'qemuBlockStorageSourceNeedsFormatLayer()' bases the decision also on the state of the passed FD, so we must initialize the passthrough data via 'qemuDomainPrepareStorageSourceFDs()' before the aforementioned call. In the test change it's visible that we didn't add the necessary 'raw' driver which allows the 'protocol' blockdev to be opened in 'rw' mode so that qemu picks the proper file descriptior while keeping the device read-only.
