cciss: Initialize scsi host max_sectors for tape drive support
commit 395d287526bb60411ff37b19ad9dd38b58ba8732 upstream. The default is too small (1024 blocks), use h->cciss_max_sectors (8192 blocks) Without this change, if you try to set the block size of a tape drive above 512*1024, via "mt -f /dev/st0 setblk nnn" where nnn is greater than 524288, it won't work right.
