I see 2 ways: 1) Since it is only an assertion and 13 is working (so 
far), you may just build 14 kernel without INVARIANTS option and later 
recreate the pool when you have time.  2) You may treat it as metadata 
corruption: import pool read-only and evacuate the data.  If you have 
recent enough snapshots you may be able to easily replicate the pool 
with all the settings to some other disk.  ZIL is not replicated, so 
corruptions there should not be a problem.  If there are no snapshots, 
then either copy on file level, or you may be able to create snapshot 
for replication in 13 (on 14 without INVARIANTS), importing pool read-write.
