dholland 03f1fbd862 In layer_lookup(), clear *vpp before returning EROFS, as otherwise a
stale value can be returned and this causes a diagnostic panic in
namei.

In relookup(), clear *vpp before calling VOP_LOOKUP, as is done in
lookup_once(), as an additional precautionary measure.

(in theory both of these fixes are not required together)

Should fix PR 47040.
