[PATCH] new cifs endianness bugs

[Al Viro <viro@ftp.linux.org.uk>]

* missing cpu_to_le64() for ChangeTime (introduced by
    [CIFS] Legacy time handling for Win9x and OS/2 part 1)
* missing le16_to_cpu() for DialectIndex (introduced by
    [CIFS] Do not send newer QFSInfo to legacy servers which can not support it)
