Perform a consistency check before deleting snapshots.
If for some reason the COW state is not fully synced to disk, but
dm-snapshot has flushed its pending merges, we do not want to delete
snapshots. Doing so could potentially leave blocks unmerged.
This situation is quite unexpected so we label it as a merge failure.
The device can recover by completely syncing the COW state, and then
rebooting, which will attempt to make forward progress on the merge.
