From: J. Bruce Fields <bfields(a)fieldses.org>

commit d327cf7449e6fd5cbac784c641770e9366faa386 upstream.

Subject: [03/34] nfs: fix acl decoding

Commit 28f566942c6b1d929f5e240e69e7081b77b238d3 "NFS: use dynamically
computed compound_hdr.replen for xdr_inline_pages offset" accidentally
changed the amount of space to allow for the acl reply, resulting in an
IO error on attempts to get an acl.
