[Qemu-devel] [PATCH 1/2] migration: Reset rather than destroy main_thread_load_event

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

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

migration_incoming_state_destroy doesn't really destroy, it cleans up.
After a loadvm it's called, but the loadvm command can be run twice,
and so destroying an init-once mutex breaks on the second loadvm.
