ofproto-dpif-upcall: Fix null pointer dereference on exit.

When revalidation occurs at the same time that a bridge is being removed
or ovs-vswitchd is exiting, xlate_lookup_ofproto() races with deletion of
the ofproto.  This caused a null pointer dereference if revalidation lost
the race.  This commit fixes the problem.
