NFS: fix an incorrect limit in filelayout_decode_layout()

Browse source

commit 769b01ea68 upstream.

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.
