[PATCH] un'fix' NCR scsi driver.

Linus,
 Current driver in your tree has been 'fixed' by someone without
understanding just how broken it was. Numerous fixes were done in 2.4
after the 2.5 split by Alan.

This patch reverts the damage the driver does in your tree, and brings
Alan's 2.4 bits over instead. Downside: It doesn't compile.
Upside: It doesn't pretend to work and corrupt data, and at least
is the right base for people to start fixing.
