[PATCH] cciss: remove partition info from CCISS_GETLUNINFO 



This patch fulfills a promise I made to Christoph sometime back.  I am
removing the partition info from the CCISS_GETLUNINFO ioctl as I was informed
my "driver had no damn business reading that structure." ;)

The application folks are to use /proc or /sys for partition info from now on.
 I am only aware of a few apps that use this ioctl and I'm not sure they ever
used the partition info.
