Bug 219285

As in the title, the below program illustrates the problem. Expected output should include line "entry: after", actual output does not:
```
entry: .
entry: ..
entry: before
```
Program:

```c
#include <unistd.h>
#include <dirent.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <stdio.h>
#include <fcntl.h>

int main() {
	system("rm -rf /tmp/dirent-problems-test-dir");
	if (mkdir("/tmp/dirent-problems-test-dir", 0755)) {
		abort();
	}

	int fd = creat("/tmp/dirent-problems-test-dir/before", 0644);
	if (fd < 0) {
		abort();
	}
	close(fd);

	DIR* dir = opendir("/tmp/dirent-problems-test-dir");

	fd = creat("/tmp/dirent-problems-test-dir/after", 0644);
	if (fd < 0) {
		abort();
	}
	close(fd);

	struct dirent* entry;
	while ((entry = readdir(dir))) {
		printf("entry: %s\n", entry->d_name);
	}

	closedir(dir);
	return 0;
}
```
