publickey: initialize the list terminator

Browse Source 
The allocation reserves `max_keys + 1` entries, while the initialization
after growth currently covers only `max_keys - keys` entries. Include
the additional reserved entry in that initialization so the list
terminator is initialized at exact capacity boundaries.
