dm thin metadata: don't issue prefetches if a transaction abort has failed
commit 2eae9e4489b4cf83213fa3bd508b5afca3f01780 upstream.
If a transaction abort has failed then we can no longer use the metadata
device. Typically this happens if the superblock is unreadable.
This fix addresses a crash seen during metadata device failure testing.
Fixes: 8a01a6af75 ("dm thin: prefetch missing metadata pages")
