[PATCH] knfsd: make sure nfsd doesn't hog a cpu forever

Being kernel-threads, nfsd servers don't get pre-empted (depending on
CONFIG).  If there is a steady stream of NFS requests that can be served
from cache, an nfsd thread may hold on to a cpu indefinitely, which isn't
very friendly.

So it is good to have a cond_resched in there (just before looking for a
new request to serve), to make sure we play nice.
