Remove unnecessary php_phongo_cursor_free_current() call

The current element is already freed at the top of this function. After that point, the element could only be intialized from first_batch_iter (after which we return immediately) or if mongoc_cursor_next() returns true (in which case we wouldn't be in this else clause).
