In migrate_set_ports() we call qdict_put_str() with a value string
which we g_strdup(). However qdict_put_str() takes a copy of the
value string, it doesn't take ownership of it, so the g_strdup()
only results in a leak:

Direct leak of 6 byte(s) in 1 object(s) allocated from:

Drop the unnecessary g_strdup() call.
