Run RAW-QFSINFO smbtorture4 test (samba unit testing utility) on WinXP CIFS
server. + captured traffic between them.

When viewing reply for SMB/TRANS2-QUERY_FS_INFO request (InfoVolume level of
interest), 'label' field of QUERY_FS_INFO data is not parsed correctly because
alignment issue: it is shifted on one byte, so UNICODE string is not recognized
as expected.

In attached example volume label is 'sys_vol'.
