dm thin: don't allow messages to be sent to a pool target in READ_ONLY or FAIL mode
commit 2a7eaea02b99b6e267b1e89c79acc6e9a51cee3b upstream.
You can't modify the metadata in these modes. It's better to fail these
messages immediately than let the block-manager deny write locks on
metadata blocks. Otherwise these failed metadata changes will trigger
'needs_check' to get set in the metadata superblock -- requiring repair
using the thin_check utility.
