I committed the change as r273727.

One issue with the commit is the specified MFC. The change will compile
on stable/10, but as far as I remember the state of sysctl patches,
it is nop on 10. It can be made functional with more patches to
nfsserver, but I prefer for the functionality to wait the needed MFCs in
kern_sysctl.c.
