  Log:
  In cluster_wbuild(), initialise b_iocmd to BIO_WRITE before calling
  buf_start() to avoid triggering a panic in softdep_disk_io_initiation()
  if b_iocmd happened to be BIO_READ. The later initialisation of
  b_iocmd in cluster_wbuild() could probably be moved to before the
  buf_start() call, but this patch keeps the change as simple as
  possible.
  
  This is reported to fix occasional "softdep_disk_io_initiation: read"
  panics, especially on NFS servers.
