If a table is read-only, also open any log and cow devices it uses read-only. Previously, even read-only devices were opened read-write internally. After patch 75f1dc0d block: check bdev_read_only() from blkdev_get() was applied, loading such tables began to fail. The patch was reverted by e51900f7 block: revert block_dev read-only check but this patch fixes this part of the code to work with the original patch.
