ofproto-dpif: Avoid dereferencing possibly null or wild pointer.

If ofpacts_len is 0 then ofpacts->type is a bad reference.

(An early draft of ofpacts used an OFPACT_END sentinel so that there was
always data there in this function, but in review the sentinel got deleted
and I did not notice that this function needed an update.)

Found by valgrind.

Bug #12847.
