Subject[156/165] nfs41: Correct offset for LAYOUTCOMMIT
2.6.39-stable review patch.  If anyone has any objections, please let us know.

From: Vitaliy Gusev <gusev.vitaliy@gmail.com>

commit 4b8ee2b82e8b0b6e17ee33feb74fcdb5c6d8dbdd upstream.

A client sends offset to MDS as it was seen by DS. As result,
file size after copy is only half of original file size in case
of 2 DS.
