yank: Unregister function when using TLS migration
After yank feature was introduced in migration, whenever migration
is started using TLS, the following error happens in both source and
destination hosts:
(qemu) qemu-kvm: ../util/yank.c:107: yank_unregister_instance:
Assertion `QLIST_EMPTY(&entry->yankfns)' failed.
This happens because of a missing yank_unregister_function() when using
qio-channel-tls.
Fix this by also allowing TYPE_QIO_CHANNEL_TLS object type to perform
yank_unregister_function() in channel_close() and multifd_load_cleanup().
Also, inside migration_channel_connect() and
migration_channel_process_incoming() move yank_register_function() so
it only runs once on a TLS migration.

Changes since v2:
- Dropped all references to ioc->master
- yank_register_function() and yank_unregister_function() now only run
once in a TLS migration.
Changes since v1:
- Cast p->c to QIOChannelTLS into multifd_load_cleanup()
