    Fix for bug #29444: crash with partition refering to table in create-select · 492f0e3f

    Problem: creating a partitioned table during name resolution for the 
    partition function we search for column names in all parts of the
    CREATE TABLE query. It is superfluous (and wrong) sometimes.
    
    Fix: launch name resolution for the partition function against
    the table we're creating.

        - set the lex->use_only_table_context before the func_expr->fix_fields()
          call to ensure we're resolving names against the table we're creating;
          then restore it back after the call.
