btrfs: abort transaction during log replay if walk_log_tree() failed

Browse Source 
If we failed walking a log tree during replay, we have a missing
transaction abort to prevent committing a transaction where we didn't
fully replay all the changes from a log tree and therefore can leave the
respective subvolume tree in some inconsistent state. So add the missing
transaction abort.
