Subject: [PATCH] Fix for BUG#20522 "RBR: CREATE TEMPORARY TABLE SELECT writes
 to binlog though unneeded". It's indeed unneeded, as slave is only interested
 in permanent tables, and permanent tables don't depend on temporary tables
 when in row-based binlogging mode. And other CREATE TEMPORARY TABLE
 (referring no table or with LIKE) already don't write the CREATE to binlog in
 row-based mode.
