qemu: Start a migration phase in qemuMigrationAnyConnectionClosed

Browse Source 
Non-postcopy case talks to QEMU monitor and thus needs to create a
nested job. Since qemuMigrationAnyConnectionClosed is called in case
there's no thread processing a migration API, we need to make the
current thread a temporary owner of the migration job to avoid "This
thread doesn't seem to be the async job owner: 0". This is done by
starting a migration phase.

While no monitor interaction happens in postcopy case and just setting
the phase (to indicate a broken postcopy migration) would be enough,
being consistent and setting the owner does not hurt anything.
