My commit b8b42ca added support for formatting the vsock
command line without actually checking if it's supported.
Add it to the per-device validation function.

This has been broken since commit v4.0.0-165-g93412bb827 which added
jobInfo->statsType enum to distinguish various statistics types. During
migration the type will always be QEMU_DOMAIN_JOB_STATS_TYPE_MIGRATION,
however the destination code consuming the statistics data from
migration cookie failed to properly set the type. So even though
everything was filled in, the type remained *_NONE and any attempt to
fetch the statistics data of a completed migration on the destination
host failed.

In commit 8bebb2b735 I've refactored how the detach of disk with a
managed persistent reservations object is handled. After the commit if
any disk with a managed PR object would be removed libvirt would also
attempt to remove the shared 'pr-manager-helper' object potentially used
by other disks.
Thankfully this should not have practical impact as qemu should reject
deletion of the object if it was still used and the rest of the code is
correct.
Fix this by removing the disk from the definition earlier and checking
if the shared/managed pr-manager-helper object is still needed.
This basically splits the detach code for the managed PR object from the
unmanaged ones. The same separation will follow for the attachment code
as well as it greatly simplifies -blockdev support for this.

When preparing qemuCaps for test cases the following is
happening:
qemuTestParseCapabilitiesArch() is called, which calls
virQEMUCapsLoadCache() which in turn calls
virQEMUCapsInitHostCPUModel() which sets qemuCaps->kvmCPU and
qemuCaps->tcgCPU.
But then the code tries to update the capabilities:
testCompareXMLToArgv() calls testUpdateQEMUCaps() which calls
virQEMUCapsInitHostCPUModel() again overwriting previously
allocated memory. The solution is to free host cpuData in
testUpdateQEMUCaps().

The nwfilter XMLs in /etc are defined as %ghost in the spec file, which
means rpm will not install them, but it will record its existence and
permissions in the database. During installation the files are copied in
a %post scriptlet from /usr/share/libvirt/nwfilter, but once libvirtd is
restarted, it will rewrite the files to add generated UUIDs.
While RPM recorded 644 mode for the XMLs, libvirt saves them with 600
and thus any future attempt to verify the libvirt-daemon-config-nwfilter
package would fail. We need to tell RPM the ghost files are supposed to
have 600 permissions.
