Similar to the fixes in 226967 and 226987, purge any name cache entries
associated with the previous vnode (if any) associated with the target of a rename(). Otherwise, a lookup of the target pathname concurrent with a rename() could re-add a name cache entry after the namei(RENAME) lookup in kern_renameat() had purged the target pathname. MFC after: 2 weeks
