Christoph Hellwig d7a4783883 md: check for NULL ->meta_bdev before calling bdev_read_only
->meta_bdev is optional and not set for most arrays.  Add a
rdev_read_only helper that calls bdev_read_only for both devices
in a safe way.

Fixes: 6f0d9689b6 ("block: remove the NULL bdev check in bdev_read_only")
