block: Do not clamp max_hw_sectors for stacking devices
Stacking devices do not have an inherent max_hw_sector limit. Set the default to INT_MAX so we are bounded only by capabilities of the underlying storage. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
