afs: Fix directory format encoding struct

Browse Source 
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.
