  Log:
    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.
