cciss: Fix scsi tape io with more than 255 scatter gather elements
commit bc67f63650fad6b3478d9ddfd5406d45a95987c9 upstream.
The total number of scatter gather elements in the CISS command
used by the scsi tape code was being cast to a u8, which can hold
at most 255 scatter gather elements. It should have been cast to
a u16. Without this patch the command gets rejected by the controller
since the total scatter gather count did not add up to the right
value resulting in an i/o error.
