block: Split bios on chunk boundaries
For h/w that advertise their block storage's underlying chunk size, it's a big performance win to not submit commands that cross them. This patch uses that criteria if it is provided. If it is not provided, this patch uses the max sectors as before. Signed-off-by: Keith Busch <keith.busch@intel.com> Signed-off-by: Jens Axboe <axboe@fb.com>
