Huawei EulerOS: CVE-2021-47168: kernel security update

In the Linux kernel, the following vulnerability has been resolved:

NFS: fix an incorrect limit in filelayout_decode_layout()

The "sizeof(struct nfs_fh)" is two bytes too large and could lead to
memory corruption. It should be NFS_MAXFHSIZE because that's the size
of the ->data[] buffer.

I reversed the size of the arguments to put the variable on the left.
