Peter Xu 39675ffffb migration: Move the yank unregister of channel_close out
It's efficient, but hackish to call yank unregister calls in channel_close(),
especially it'll be hard to debug when qemu crashed with some yank function
leaked.

Remove that hack, but instead explicitly unregister yank functions at the
places where needed, they are:

  (on src)
  - migrate_fd_cleanup
  - postcopy_pause

  (on dst)
  - migration_incoming_state_destroy
  - postcopy_pause_incoming
