afs: prevent double cell registration

kafs doesn't check if the cell already exists - so if you do an echo "add
newcell.org 1.2.3.4" >/proc/fs/afs/cells it will try to create this cell
again.  kobject will also complain about a double registration.  To prevent
such problems, return -EEXIST in that case.
