Assertion `active() == false' failed with "XA START.."

Details

    Description

      Although MariaDB Galera Cluster does not support XA transactions but it still shouldn't crash server.

      1. create a new db and a table
      2. input a value
      3. XA START 'test';

      here where it crashed I received in the log

      mariadbd: /home/jenkins/workspace/MariaDBE-Custom-bintar/label/rhel-7/wsrep-lib/src/transaction.cpp:123: int wsrep::transaction::start_transaction(const wsrep::transaction_id&): Assertion `active() == false' failed.

      This could be because you hit a bug. It is also possible that this binary
      		 
      or one of the libraries it was linked against is corrupt, improperly built,
      		 
      or misconfigured. This error can also be caused by malfunctioning hardware.
      		 
       
      		 
      To report this bug, see https://mariadb.com/kb/en/reporting-bugs
      		 
       
      		 
      We will try our best to scrape up some info that will hopefully help
      		 
      diagnose the problem, but since we have already crashed, 
      something is definitely wrong and this may fail.

          Currently using XA-transactions could cause whole cluster to either crash or go to inconsistent state. We could refuse all XA-transactions from user, however there are some internal usage of XA that can't be at the moment refused.

          I can repeat crash but different assertion. In my opinion this should not crash. Assertions like this should inform us what is actual state() value.
