inet: remove old fragmentation hash initializing
All fragmentation hash secrets now get initialized by their
corresponding hash function with net_get_random_once. Thus we can
eliminate the initial seeding.
Also provide a comment that hash secret seeding happens at the first
call to the corresponding hashing function.
