Joe Thornber 2eae9e4489 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")
