[PATCH] nfs: sysctl's should use USER_HZ not HZ

[Stephen Hemminger <shemminger-ZtmgI6mnKB3QT0dZR+AlfA@public.gmane.org>]

There is no good way to tell what the internal value of kernel HZ is
from userspace, so all administrative interfaces are supposed to use
either USER_HZ (100) or other absolute time units.  Two of the NFS sysctl
values are still using HZ, and can be simply converted to USER_HZ.
