SVN rev 185557 on 2008-12-02 11:14:16Z by kib
Shared lookup makes it possible to create several negative cache
entries for one name. Then, creating inode with that name would remove
one entry, leaving others dormant. Reclaiming the vnode would uncover
negative entries, causing false return of ENOENT from the calls like
stat, that do not create inode.
Prevent creation of the duplicated negative entries.
