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.
