Subject: [PATCH] nvme: Check hw sectors before setting chunk sectors

Keith,

> Some devices with IDs matching the "stripe" quirk don't actually have
> this quirk, and don't have an MDTS value. When MDTS is not set, the
> driver sets the max sectors to UINT_MAX, which is not a power of 2,
> hitting a BUG_ON from blk_queue_chunk_sectors. This patch skips
> setting chunk sectors for such devices.
