Subject: sanitize dump payload: fix crash with empty set with listpack
 encoding (#11519)

The following example will create an empty set (listpack encoding):
```
> RESTORE key 0
"\x14\x25\x25\x00\x00\x00\x00\x00\x02\x01\x82\x5F\x37\x03\x06\x01\x82\x5F\x35\x03\x82\x5F\x33\x03\x00\x01\x82\x5F\x31\x03\x82\x5F\x39\x03\x04\xA9\x08\x01\xFF\x0B\x00\xA3\x26\x49\xB4\x86\xB0\x0F\x41"
OK
> SCARD key
(integer) 0
> SRANDMEMBER key
Error: Server closed the connection
```

In the spirit of #9297, skip empty set when loading RDB_TYPE_SET_LISTPACK.
Introduced in #11290
