  Modified files:
    sys/miscfs/union     union_vnops.c 
  Log:
  Fixed vnode corruption by undefined case in union_lookup().  When
  uerror == 0 && lerror == EACCES, lowervp == NULLVP and union_allocvp
  doesn't find existing union node and new union node is created.
  
  Sicne it is dificult to cover all the case, union_lookup always
  returns when union_lookup1() returns EACCES.
