The AFS directory format structure, union afs_xdr_dir_block::meta, has too many alloc counter slots declared and so pushes the hash table along and over the data. This doesn't cause a problem at the moment because I'm currently ignoring the hash table and only using the correct number of alloc_ctrs in the code anyway. In future, however, I should start using the hash table to try and speed up afs_lookup(). Fix this by using the correct constant to declare the counter array.
