Jon Olav Hauglid 99b1d5ea24 Bug #54105 assert in MDL_context::release_locks_stored_before ...

The problem was that SHOW CREATE EVENT released all metadata locks
held by the current transaction. This made any exisiting savepoints
invalid, triggering the assert when ROLLBACK TO SAVEPOINT later
was executed.

This patch fixes the problem by making sure SHOW CREATE EVENT only
releases metadata locks acquired by the statement itself.

Test case added to event_trans.test.
