### Description
The kamailio 5.6.0 segfault on restart
### Troubleshooting
Kamailio sends a Ping Options packet to the registered UA with keepalive functional of
usrloc module. When you restart the kamailio with the systemctl restart kamailio command,
the kamailio is segfault. In version the 5.5.4 same as in 5.6.0
#### Reproduction
1. Enabled keepalive functional of usrloc module.
2. Registered UA on wss protocol.
3. Restart the kamailio
parameters on usrloc module
```

Crash was at shutdown, websocket module probably already destroyed when usrloc tried to
