afs: Fix premature cell exposure through /afs
AFS cell records are prematurely exposured through the /afs dynamic root by
virtue of adding them immediately to the net->cells_dyn_ino IDR when the
cell is allocated rather than when it is added to the lookup tree. This
allows a candidate record to be accessed, even if it's actually a duplicate
or not published yet.
Fix this by not adding the cell to cells_dyn_ino until it's confirmed
non-duplicate and is being published. A flag is then used to record
whether it is added to the IDR to make removal from the IDR conditional.
