qemu: migration: Properly parse memory hotplug migration flag

Since the flag was not enabled when 'eating' the migration cookie,
libvirt reported a bogus error when memory hotplug was enabled:

 unsupported migration cookie feature memory-hotplug

The error was ignored though due to a bug in the code so it slipped
through testing.
