7287cbd46e2d6fb582ca78c3cb49b1e53d91a761 migration: move vm_old_running into global state
Firstly, it was passed around. Let's just move it into MigrationState
just like many other variables as state of migration, renaming it to
vm_was_running.
One thing to mention is that for postcopy, we actually don't need this
knowledge at all since postcopy can't resume a VM even if it fails (we
can see that from the old code too: when we try to resume we also check
against "entered_postcopy" variable). So further we do this:
- in postcopy_start(), we don't update vm_old_running since useless
- in migration_thread(), we don't need to check entered_postcopy when
resume, since it's only used for precopy.
Comment this out too for that variable definition.
