sysutils/dvdisaster coredumps on FreeBSD/amd64 RELENG_9

Hi C. P. and all,

Thanks for the report. You're right about the memory
corruption occurring in the line you commented out;
it's a data size mismatch triggered by a size change
in struct scsi_sense_data.

The attached patch corrects the problem.
A new upstream release will be made after some
more testing.

Cheers,
   Carsten
