[PATCH] knfsd: Correct reserved reply space for read requests.

NFSd makes sure there is enough space to hold the maximum possible reply
before accepting a request.  The units for this maximum is (4byte) words.
However in three places, particularly for read request, the number given is
a number of bytes.

This means too much space is reserved which is slightly wasteful.

This is the sort of patch that could uncover a deeper bug, and it is not
critical, so it would be best for it to spend a while in -mm before going
in to mainline.

(akpm: target 2.6.17-rc2, 2.6.16.3 (approx))
