Since commit 79eadafeb1b4 udpif_stop_threads() doesn't delete datapath
flows while called from udpif_destroy(). This means that ukeys are
not cleaned up either. So, hash maps in udpif->ukeys[] might still
contain valid pointers to ukeys that should be destroyed before
destroying the hash map itself:
