    afs: do not leak stale data in buffers
    
    Similar to the previous commit, zero out the buffer when fetching
    a new slot, to avoid the possibility of leaving stale data in
    a reused buffer.
    
    We are not supposed to write such stale data back to a fileserver,
    but this is an extra precaution in case of bugs elsewhere -- memset
    is not as expensive as it was in the 1980s.
