  Log:
  MFC: Fix a problem that occurs when truncating files on NFSv3 mounts: we
  need to set np->n_size back to the desired size again after calling
  nfs_meta_setsize(), since it could end up in nfs_loadattrcache() getting
  called, which would change n_size back to the value it had before the
  truncate request was issued. The result of this bug is that the size info
  cached in the nfsnode becomes incorrect, lseek(fd, ofs, SEEK_END) seeks
  past the end of the file, stat() returns the wrong size, etc.
