cciss: fix cciss_revalidate panic

If you delete a logical drive, and then run BLKRRPART (e.g. via fdisk)
on a logical drive which is "after" the deleted logical drive in the h->drv[]
array, then cciss_revalidate panics because it will access the null pointer
h->drv[x] when x hits the deleted drive.
