[PATCH] afs: Documentation updates

[Anton Blanchard]

I fixed some issues with the afs documentation, found when testing afs
on ppc64:

- Update afs features: reading/writing, local caching
- Typo in kafs sysfs debug file
- Use modprobe instead of insmod in example
- Update IPs for grand.central.org
