cciss: Initialize scsi host max_sectors for tape drive support

cciss: Initialize scsi host max_sectors for tape drive support

BugLink: http://bugs.launchpad.net/bugs/987337

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.
