Sergei Golubchik 91599701d0 Bug#29363867: LOST CONNECTION TO MYSQL SERVER DURING QUERY ...

plugin variables in SET  only locked the plugin till the end of the
statement. If SET with a plugin variable was prepared, it was possible
to uninstall the plugin before EXECUTE. Then EXECUTE would crash,
trying to resolve a now-invalid pointer to a disappeared variable.

Fix: keep plugins locked until the prepared statement is closed.
