A critical thing the ServeRAID driver MUST do is hide the physical DASDI
devices from the OS. It does this by intercepting the INQUIRY commands.

In recent 2.6.15 testing, I discovered this to be failing.

The cause was the driver assuming that the INQUIRY response data was in a
simple single buffer, when it was actually a 1 element scatter gather list.

This patch makes ips always look at the correct data when examining an
INQUIRY response.
