    gNFS: Set default outstanding RPC limit to 16
    
    Backport of http://review.gluster.org/#/c/6696/
    
    With 64, NFS server hangs with large I/O load (~ 64 threads writing
    to NFS server). The test results from Ben England (Performance expert)
    suggest to set it as 16 instead of 64.
