    Handle net option for nfs in kdump.conf correctly
    
    Resolve: bug 807521
    
    The fix is easy.
    
    Command sed should be called with option -n to remain slience when DUMP_TARGET
    is a nfs server like 'nfs.server:/mnt/testarea/nfs'.
    
    Then nfs function check_ssh_config will return 1 to not to config nfs like a
    ssh dump
