Fixed LP bug #892725.

Browse Source 
A non-first execution of a prepared statement missed a call of the
TABLE_LIST::process_index_hints() method in the code of the function
setup_tables().
At some scenarios this could lead to the choice of a quite inefficient
execution plan for the base query of the prepared statement.
