latest svn code.

since the get configuration cmd only allocated 8 bytes, so even the
response packet shows that it can have 322bytes data to return, it will
only return 8 bytes. this conform the scsi standard.

but i guess the dissector tried to decode all data base on that 322
bytes, then it report a malform packet here.

any idea on this?
