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

upstream commit: fcc7c09d94be7b75c9ea2beb22d0fae191c6b4b9
Discovered at Connnectathon 2009...
The buffer format byte and the pad are transposed in NT_RENAME calls
(which are used to set hardlinks). Most servers seem to ignore this
fact, but NetApp filers throw back an error due to this problem. This
patch fixes it.
