Fix bug #13180 thd->allow_sum_funcs wasn't reset before query processing.

Browse Source 
thd->allow_sum_func was left 'true' after previous statement thus allowing
sum funcs to be present in conditions.

thd->allow_sum_func should be set to 0 for each query and each prepared
statement reinitialization. This is done in lex_start() and 
reset_stmt_for_execute().
