The SMB dce_iface and dce_opnum keywords don't match.

Following rule and the associated pcap can be used to test this behavior:

alert smb any any -> any any (\
      msg: "SMB-DCE EnumPrinterDrivers";\
      dce_iface: 12345678-1234-abcd-ef00-0123456789ab;\
      dce_opnum: 10;\
      sid: 1;\
      )
