Subject: afs: proc cells and rootcell are writeable
Both proc files are writeable and used for configuring cells. But
there is missing correct mode flag for writeable files.
Without this patch it is not possible to write to cells and rootcell files
which means that it is not possible to add new servers to cells, so it is
not possible to access afs disks and afs driver is unusable.
