Monty 4277c173a9 MDEV-15149 Assert upon concurrent creating / querying sequences
MDEV-15117 Server crashes in in open_and_process_table or ASAN
heap-use-after-free in is_temporary_table upon creating/flushing
sequences.

Problem was that sequence_insert closed and reopened the like table
without proper locking.  Fixed by ensuring that the like table is
not reopened in sequence_insert
