cluster/afr: Fail open on split-brain
Problem: Append on a file with split-brain succeeds. Open is intercepted by open-behind, when write comes on the file, open-behind does open+write. Open succeeds because afr doesn't fail it. Then write succeeds because write-behind intercepts it. Flush is also intercepted by write-behind, so the application never gets to know that the write failed. Fix: Fail open on split-brain, so that when open-behind does open+write open fails which leads to write failure. Application will know about this failure.
