Rafael Zalamena 95a99382cb bgpd: fix crash on daemon exit 
Don't attempt to send BFD daemon a message to remove the peer
registration on daemon exit, otherwise we'll access a dangling
interface pointer and we'll crash.

This crash was not previosly possible because the function that built
the message was passing the interface pointer but not using it due to
the exit condition.

In `lib/bfd.c`:

```
void bfd_peer_sendmsg(struct zclient *zclient, struct bfd_info *bfd_info,
		      int family, void *dst_ip, void *src_ip, char *if_name,
		      int ttl, int multihop, int cbit, int command,
		      int set_flag, vrf_id_t vrf_id)
{
	struct bfd_session_arg args = {};
	size_t addrlen;

	/* Individual reg/dereg messages are suppressed during shutdown. */
	if (CHECK_FLAG(bfd_gbl.flags, BFD_GBL_FLAG_IN_SHUTDOWN)) {
		if (bfd_debug)
			zlog_debug(
				"%s: Suppressing BFD peer reg/dereg messages",
				__func__);
		return;
	}
```
