MDEV-19680:: Assertion `!table || (!table->read_set || bitmap_is_set(table->read_set, field_index) || (!(ptr >= table->record[0] && ptr < table->record[0] + table->s->reclength)))' or alike failed upon SELECT with mix of functions from simple view

Set read_set bitmap for view from the JOIN::all_fields list instead of JOIN::fields_list
