…ey-io#2944)

When import-mode is yes, we might be able to set an expired TTL. At the
same time,
commands like EXPIREAT/EXPIRE do not restrict TTL from being negative.
After we
set import-mode to no, server will crash at:
```
 int activeExpireCycleTryExpire(serverDb *db, robj *val, long long now, int didx) { 
     long long t = objectGetExpire(val); 
     serverAssert(t >= 0); 
```

In this case, we restrict ttl from being negative in
expireGenericCommand, we simply
change the expiration time to 0 to mark the key as expired since in
import-mode, the
import-source client can always read the expired keys anyway.

import-mode was introduced in valkey-io#1185
