dm: fix opening log and cow devices for read only tables
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 75f1dc0d076d1c1168f2115f1941ea627d38bd5a
block: check bdev_read_only() from blkdev_get()
was applied, loading such tables began to fail. The patch
was reverted by e51900f7d38cbcfb481d84567fd92540e7e1d23a
block: revert block_dev read-only check
but this patch fixes this part of the code to work with the original patch.
