When error happen in multifd_send_thread, it use error_copy to set migrate error in
multifd_send_terminate_threads(). We should call error_free after it.
Similarly, fix another two places in multifd_recv_thread/multifd_save_cleanup.

When error happen in multifd_new_send_channel_async, 'sioc' will not be used
to create the multifd_send_thread. Let's free it to avoid a memleak. And also
do error_free after migrate_set_error() to avoid another leak in the same place.
