[sr-dev] [kamailio] jsonrpc-c notification does not free shm memory (#296)

[zxcpoiu]

I compiled brand new kamailio, and use my kamailio.cfg

```
$> git branch -v
* master ec0ba37 jsonrpc-c: proper error handling for pipe cmd callback

$> kamcmd core.info
{
	version: kamailio 4.4.0-dev2
	id: ec0ba3 
	compiler: gcc 4.7.2
	compiled: 22:33:06 Aug 27 2015
	flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES
}
```

#### Strange Result

* **It NEVER crash**
* use `kamcmd core.shmmem` shows still consumed shmmem and did not free
* when shmmem free reaches 0 ( or near 0 ), it frees all memory suddenly, and free mem restore max.
* when restored all mem, the sipp shows:
`Error on TCP connection, remote peer probably closed the socket: Connection reset by peer.` 
and the test finished.
* in the mean time, in kamailio syslog, it only shows:

```
ERROR: <core> [tcp_read.c:271]: tcp_read_data(): error reading: Connection reset by peer (104)
ERROR: <core> [tcp_read.c:1296]: tcp_read_req(): ERROR: tcp_read_req: error reading
```

seems like all fd were gone.
