Davi Arnaut f7e7718560 Bug#41889: Test main.innodb_bug38231 is failing w/embedded server (server crash) ...

The problem is that a mysql connection instance is not thread-safe
and reentrant, meaning that it can't be used concurrently and can't
be re-entered while it's already running. This applies for any form
of the server (embedded or not), but this rule can be violated in a
test case if the test sends a new command without waiting for the
result of previous command that was sent asynchronously and this can
lead to hangs when over a network or to crashes under embedded server
as the server query execution path will be re-entered concurrently
with the same connection structure.

The solution is to rework the test case so that the aforementioned
rule is obeyed.

mysql-test/t/innodb_bug38231.test:
  Remove con3 as it is not necessary to reproduce the test case
  and might cause problems as there is no guarantee on which
  LOCK TABLE request will succeed first. Also, wait for statement
  result before sending a new one on the same connection.
