[kamailio/kamailio] cdp: disconnect_serviced_peer Causing the service process to crash (Issue #3999)

### Description
hi, I encountered a problem where the CDP module is extremely prone to process crashes.
The following are screenshots of the logs and core files. I couldn't find the
exception code that caused the problem, but I suspect that the TCP link was properly
established, but the peer did not initialize or handle the exception properly, resulting
in an exception when the packet was parsed incorrectly and disconnected later. In
addition, since the socket is not a normal peer, it will constantly rebuild the chain, but
the CDP does not recognize and process it properly. The socket will continue to grow, but
the number of peers will not increase.

Hey liangbaolin,
I tried to look into this, but the backtrace is a bit strange, because
those line numbers don't match up at all -
https://github.com/kamailio/kamailio/blob/5.8.1/src/modules/cdp/receiver.c#…
Or maybe I'm looking at a different version than you are, or the core is
from a different version of the source code?
Cheers,
-Dragos

Description
hi, I encountered a problem where the CDP module is extremely prone to
process crashes. The following are screenshots of the logs and core files.
I couldn't find the exception code that caused the problem, but I suspect
that the TCP link was properly established, but the peer did not initialize
or handle the exception properly, resulting in an exception when the packet
was parsed incorrectly and disconnected later. In addition, since the
socket is not a normal peer, it will constantly rebuild the chain, but the
CDP does not recognize and process it properly. The socket will continue to
grow, but the number of peers will not increase.

Sorry, I have made some feature customization in my program code, but the core code has
not changed. It involves TCP link building and peer management, which are consistent. The
code lines indicated in the logs should not match the original version. Here, I provide my
logs corresponding to the actual code
`
tv.tv_sec = 1;
tv.tv_usec = 0;
n = select(max + 1, &rfds, 0, &efds, &tv);
if(n == -1) {
if(shutdownx && *shutdownx)
return 0;
273 LM_ERR("select_recv(): %s\n", strerror(errno));
for(sp = serviced_peers; sp; sp = sp2) {
sp2 = sp->next;
disconnect_serviced_peer(sp, 0);
if(sp->p && sp->p->is_dynamic)
drop_serviced_peer(sp, 0);
}
sleep(1);
break;
} else if(n) {
if(FD_ISSET(fd_exchange_pipe_local, &rfds)) {
/* fd exchange */
LM_DBG("select_recv(): There is something on the fd "
"exchange pipe\n");
`
