LOOKUP_MOUNTPOINT: we are cleaning "jumped" flag too late
commit 4f0ed93fb92d3528c73c80317509df3f800a222b upstream.
That (and traversals in case of umount .) should be done before
complete_walk(). Either a braino or mismerge damage on queue
reorders - either way, I should've spotted that much earlier.
