a859723912 nicer handling of DISCONNECTED flag when we update the node flags from 
a remote message

69f3a09e6f when a remote node has sent us a message to update the flags for a node, 
dont let those messages modify the DISCONNECTED flag.

the DISCONNECTED flag must be managed locally since it describes whether 
the local node can communicate with the remote node or not

b871c3e365 a better way to fix the DISCONNECT|BANNED vs DISCONNECT bug 
(This used to be ctdb commit 5c638d7731c5a268de02d3a37828ac7aec9a12de)

3499c8c673 when checking the nodemap flags for consitency while monitoring the 
cluster,   we cant check that both the BANNED and the DISCONNECTED flags 
are both set at the same time   since if a node becomes banned just 
before it is DISCONNECTED   there is no guarantee that all other nodes 
will have seen the BANNED flag.

So we must first check the DISCONNECTED flag only   and only if the 
DISCONNECTED flag is not set should we check the BANNED flag.


othervise this can cause a recovery loop while some nodes thing the 
disconnected node is DISCONNECTED|BANNED and other think it is just 
DISCONNECTED
