fs/namei.c: keep track of nd->root refcount status

And I'm not going to abstain from folding the trivial fix
(LOOKUP_ROOT_GRABBED had been given the same value as LOOKUP_EMPTY)
into the commit. Sorry. I don't know how to tell CI systems out
there about cases like that ("earlier version of this commit used
to have a bug, fix folded in"). Something like
Supersedes: <list of sha1>
might or might not be useful for tracking; not sure.
