rbd: disallow read-write partitions on images mapped read-only
If an image is mapped read-only, don't allow setting its partition(s) to read-write via BLKROSET: with the previous patch all writes to such images are failed anyway. If an image is mapped read-write, its partition(s) can be set to read-only (and back to read-write) as before. Note that at the rbd level the image will remain writeable: anything sent down by the block layer will be executed, including any write from internal kernel users.
