Chunwei Chen 493492559e Limit number of tasks shown in taskq proc
To prevent holding tq_lock for too long.

Before zfsonlinux/zfs@8e71ab9, hogging delay tasks and cat /proc/spl/taskq
would easily cause a lockup. While that bug has been fixed. It's probably
still a good idea to do this just in case task lists grow too large.
