MDEV-31903 Server crashes in _ma_reset_history upon UNLOCK table with auto-create history partitions

Browse Source 
When INSERT does auto-create for t1 all its handler instances are
closed by alter_close_table(). At this time down the stack
maria_close() clears share->state_history. Later when we unlock the
tables Aria transaction manager accesses old share instance (the one
before t1 was closed) and tries to reset its state_history.

The problem is maria_close() didn't remove table from transaction's
list (used_tables). The fix does _ma_remove_table_from_trnman() which
is triggered by HA_EXTRA_PREPARE_FOR_RENAME.
