CVE-2021-47168 NFS: fix an incorrect limit in filelayout_decode_layout()

In the Linux kernel, the following vulnerability has been resolved: NFS: fix an incorrect limit in filelayoutdecodelayout The "sizeofstruct nfsfh" is two bytes too large and could lead to memory corruption. It should be NFSMAXFHSIZE because that's the size of the -data buffer. I reversed the size...
