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.
