Removed redundant SE lock for tmp tables

Browse Source 
CREATE TEMPORARY TABLE locks SE plugin 6 times. 5 of these locks are
released by the end of the statement. And only 1 acquired by
init_from_binary_frm_image() / plugin_lock() remains.

The lock removed in this patch was clearly redundant.

Part of MDEV-17805 - Remove InnoDB cache for temporary tables.
