nfs: Remove unused xdr page offsets in getacl/setacl arguments
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. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
