SVN rev 208300 on 2010-05-19 15:06:09Z by attilio
Fix a race between ngs_rcvmsg() and soclose() which closes the control
socket while it is still in use.
priv->ctlsock is checked at the top of the function but without any
lock held, which means the control socket state may certainly change.
Add a similar protection to ngs_shutdown() even if a race is unlikely
to be experienced there.
