[RFC v3 40/45] nfs: Remove unused xdr page offsets in getacl/setacl arguments

[Andreas Gruenbacher]

The arguments passed around for getacl and setacl xdr encoding, struct
nfs_setaclargs and struct nfs_getaclargs, both contain an array of pages, an
offset into the first page, and the length of the page data. The offset is
unused as it is always zero; remove it.
