syncbase/vsync: closing discovery channel

Fix a bug in the neighborhood peer-discovery scanner.  When the context
is cancelled during Syncbase shutdown, the discovery channel is closed.
Detect that and terminate the neighborhood scan.  Also prioritize the
detection of the sync channel closing, as done in other sync threads.
