hastd: socket leakage on worker exit

[Mikolaj Golub]

Hi,

Playing with HAST I have noticed the following issue with hasd:

....
Apr 10 22:32:36 hastb hastd: [storage] (secondary) Split-brain detected, exiting.
Apr 10 22:32:36 hastb hastd: [storage] (secondary) Worker process failed (pid=6474, status=78).
Apr 10 22:32:56 hastb hastd: [storage] (secondary) Split-brain detected, exiting.
Apr 10 22:32:56 hastb hastd: [storage] (secondary) Worker process failed (pid=6475, status=78).
Apr 10 22:32:56 hastb hastd: [storage] (secondary) Unable to create control sockets be: Too many open files

And sockstat:

root hastd 711 4 stream /var/run/hastctl
root hastd 711 5 tcp4 *:8457 *:*
root hastd 711 7 dgram -> /var/run/logpriv
root hastd 711 8 stream (not connected)
root hastd 711 9 stream -> ??
root hastd 711 10 stream -> ??
root hastd 711 12 stream -> ??
root hastd 711 13 stream -> ??
root hastd 711 14 stream -> ??
root hastd 711 15 stream -> ??
[ ... and so on .. ]

The patch below has fixed the issue.
