raid5: allow arbitrary max_hw_sectors raid5 will split bio to proper size internally, there is no point to use underlayer disk's max_hw_sectors. In my qemu system, without the change, the raid5 only receives 128k size bio, which reduces the chance of bio merge sending to underlayer disks. Signed-off-by: Shaohua Li <shli@fb.com>
