Fix bug #11416 Server crash if using a view that uses function convert_tz

When parser parses function convert_tz it loads available timezone tables in
thd->lex->time_zone_tables_used. But view have another lex that main query.
Thus time_zone_tables_used of main query left uninitialized.
When Item_func_conver_tz is fixed it takes timezone tables from main query
and later when it executed it assumes that timezone tables are loaded and
failed that assertion.
