  SVN rev 211930 on 2010-08-28 08:57:15Z by pjd
  
  There is a bug in vfs_allocate_syncvnode() failure handling in mount code.
  Actually it is hard to properly handle such a failure, especially in MNT_UPDATE
  case. The only reason for the vfs_allocate_syncvnode() function to fail is
  getnewvnode() failure. Fortunately it is impossible for current implementation
  of getnewvnode() to fail, so we can assert this and make
  vfs_allocate_syncvnode() void. This in turn free us from handling its failures
  in the mount code.
