Now that I can run sparse again, spotted two recent minor endian

Subject: [PATCH] smb3: cleanup some recent endian errors spotted by updated
 sparse

Now that sparse has been fixed, it spotted a couple recent minor
endian errors (and removed one additional sparse warning).

Thanks to Luc Van Oostenryck for his help fixing sparse.
