kernel: ctlfs: Do not reclaim ctlfs entries

There will likely be multiple times the reference count of a ctlfs entry
will hit zero. Several programs may open and close a ctlfs node more
than once and as these are hardwired kernel objects, they must always
stay present. At the most we may set the vp->data field to NULL,
indicating that it is currently unused.
