4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tejun Heo <tj@kernel.org>

commit 1488a1e3828d60d74c9b802a05e24c0487babe4e upstream.

Since 34b48db66e08 ("block: remove artifical max_hw_sectors cap"),
max_sectors is no longer limited to BLK_DEF_MAX_SECTORS and LITE-ON
CX1-JB256-HP keeps timing out with higher max_sectors.  Revert it to
the previous value.
