Add debug to vdev_label_read_config when txg check fails
This changes were added to help debug issue #9187.
Essentially, in the original bug, vdev_validate() seems to fails in vdev_label_read_config() and prints "failed reading config". This could happen because either:
1. The labels are actually corrupt and zio_wait() fails for all of them
2. The labels were discarded because they didn't pass the txg check.
Beyond #9187, having debug info when case 2 happens could be useful in other scenarios, such as zpool import.
