dm thin metadata: don't issue prefetches if a transaction abort has failed
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")
