    afs: Bound afs_DoBulkStat dir scan
    Currently, afs_DoBulkStat will scan the entire directory blob, looking
    for entries to stat. If all or almost all entries are already stat'd,
    we'll scan through the entire directory, doing nontrivial work on
    each entry (we grab afs_xvcache, at least). All of this work is pretty
    pointless, since the entries are already cached and so we won't do
    anything. If many processes are trying to acquire afs_xvcache, this
    can contribute to performance issues.
    To avoid this, provide a constant bound on the number of entries we'll
    search through: nentries * 4. The current arbitrary limits cap
    nentries at 30, so this means we're capping the afs_DoBulkStat search
    to 120 entries.
