Subject: Handle big endianness in NTLM (ntlmv2) authentication

From: Steve French <smfrench@xxxxxxxxxx>

commit fdf96a907c1fbb93c633e2b7ede3b8df26d6a4c0 upstream.

This is RH bug 970891
Uppercasing of username during calculation of ntlmv2 hash fails
because UniStrupr function does not handle big endian wchars.

Also fix a comment in the same code to reflect its correct usage.

[To make it easier for stable (rather than require 2nd patch) fixed
this patch of Shirish's to remove endian warning generated
by sparse -- steve f.]
