traffic_packets: replace level 102 to 101 for packet_srvsvc_21

Level 102 will cause WERR_ACCESS_DENIED error against Windows, because:

    > If the level is 102 or 502, the Windows implementation checks whether
    > the caller is a member of one of the groups previously mentioned or
    > is a member of the Power Users local group.

It passed against Samba since this check is not implemented by Samba yet.
