[PULL 01/26] migration: Properly destroy variables on incoming side

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: Peter Xu <peterx@redhat.com>

In migration_incoming_state_destroy(), we've got a few variables that aren't
destroyed properly, namely:

    main_thread_load_event
    postcopy_pause_sem_dst
    postcopy_pause_sem_fault
    rp_mutex

Destroy them properly.
