The current gdth driver crashes the machine with a panic() when
accessing certain tape drives, really not a good thing for stable.

This patch fixes it, tested by me and acknowledged by Achim.
See http://lkml.org/lkml/2006/10/13/60 and
http://lkml.org/lkml/2006/10/12/35 for further reference.

The patch is against Linus' 2.6.20

Bye,

Joerg
