Fix syntax error of DONT_FAIL_ON_CRC_ERROR in archive_read_support_fo… (#2066)

Following code snippet in
`libarchive/archive_read_support_format_7zip.c` causing a build fail
while enable the `DONT_FAIL_ON_CRC_ERROR`

```
/* Check the EncodedHeader CRC.*/
		if (r == 0 && zip->header_crc32 != next_header_crc) {
			archive_set_error(&a->archive, -1,
#ifndef DONT_FAIL_ON_CRC_ERROR
			    "Damaged 7-Zip archive");
			r = -1;
#endif
```

I fix it like this:

```
/* Check the EncodedHeader CRC.*/
		if (r == 0 && zip->header_crc32 != next_header_crc) {
#ifndef DONT_FAIL_ON_CRC_ERROR
			archive_set_error(&a->archive, -1,
			    "Damaged 7-Zip archive");
			r = -1;
#endif
```
