Tao Ma 5cc3bf2786 ocfs2: Reconnect after idle time out. 
Currently, o2net connects to a node on hb_up and disconnects on
hb_down and net timeout.

It disconnects on net timeout is ok, but it should attempt to
reconnect back. This is because sometimes nodes get overloaded
enough that the network connection breaks but the disk hb does not.
And if we get into that situation, we either fence (unnecessarily)
or wait for its disk hb to die (and sometimes hang in the process).

So in this updated scheme, when the network disconnects, we keep
attempting to reconnect till we succeed or we get a disk hb down
event.

If the other node is really dead, then we will eventually get a
node down event. If not, we should be able to connect again and
continue.
