ofproto-dpif-xlate: Do not exit if peer bridge exits.

The fact that the peer bridge exits (for any reason) does not mean
that the original bridge should exit.  Specifically, if the peer
bridge recirculates (which typically modifies the packet), the
original bridge must continue processing with the original, not the
recirculated packet!
