cifs: fix unaligned accesses in cifsConvertToUCS
Move cifsConvertToUCS to cifs_unicode.c where all of the other unicode related functions live. Have it store mapped characters in 'temp' and then use put_unaligned_le16 to copy it to the target buffer. Also fix the comments to match kernel coding style.
