[PATCH] md: Make MD device-is-idle test check whole device, not partition.
When resyncing an array, md will back off if it detects other
activity on the device. This used to be based on the whole
device, not the partition, but recent changes made it only
check IO on the partition.
This patch causes all sync_io accounting to be done on the
whole device (bdev->bd_contains).
