@details
Set ha_data pointer (storage engine per-connection information).
To avoid unclean deactivation (uninstall) of storage engine plugin
in the middle of transaction, additional storage engine plugin
lock is acquired.
If ha_data is not null and storage engine plugin was not locked
by thd_set_ha_data() in this connection before, storage engine
plugin gets locked.
If ha_data is null and storage engine plugin was locked by
thd_set_ha_data() in this connection before, storage engine
plugin lock gets released.
If handlerton::close_connection() didn't reset ha_data, server does
it immediately after calling handlerton::close_connection().
