All callers pass the equivalent of looking up whether qemu supports
QEMU_CAPS_QMP_QUERY_NAMED_BLOCK_NODES_FLAT. Use
'mon->queryNamedBlockNodesFlat' directly and refactor all callers.

'query-named-block-nodes' in non-flat mode returns redundantly nested
data under the 'backing-image' field. Fortunately we don't need it when
updating the capacity stats.
This function was unfortunately not fixed originally when the support
for flat mode was added. Use the flat cached in the monitor object to
force flat mode if available.

Rather than having callers always pass this flag store it in the
qemuMonitor object. Following patches will convert the code to use this
internal flag.
In the future this will also simplify removal when all supported qemu
versions will support the new mode.

In recent commits migration of TPM on shared storage was

not notice that clang build fails due to missing break; at the
end of some (empty) cases in switch() statements.

When using shared storage there is no need to apply security labels on the
storage since the files have to have been labeled already on the source
side and we must assume that the source and destination side have been
setup to use the same uid and gid for running swtpm as well as share the
same security labels. Whether the security labels can be used at all
depends on the shared storage and whether and how it supports them.

Pass the --migration option to swtpm if swptm supports it (starting
with v0.8) and if the TPM's state is written on shared storage. If this
is the case apply the 'release-lock-outgoing' parameter with this
option and apply the 'incoming' parameter for incoming migration so that
swtpm releases the file lock on the source side when the state is migrated
and locks the file on the destination side when the state is received.
If a started swtpm instance is running with the necessary options of
migrating with share storage then remember this with a flag in the
virDomainTPMPrivateDef.
Report an error if swtpm does not support the --migration option and an
incoming migration across shared storage is requested.
