Subject: [ 061/171] ceph: osd_client: fix endianness bug in osd_req_encode_op()

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Elder <elder@...awmhost.com>

(cherry picked from commit 065a68f9167e20f321a62d044cb2c3024393d455)

>>From Al Viro <viro@...iv.linux.org.uk>

Al Viro noticed that we were using a non-cpu-encoded value in
a switch statement in osd_req_encode_op().  The result would
clearly not work correctly on a big-endian machine.
