  Log:
  Fix an invalidation case that tends to occur under load on NFS servers or
  on machines with low amounts of main memory.  The buf was being recursively
  locked and a ref count assertion was wrong.
  
  The code-path was previously untested and would dependably panic the
  machine every time prior to the fix.
