NFS: Fix size of NFSACL SETACL operations
commit d683cc49daf7c5afca8cd9654aaa1bf63cdf2ad9 upstream.
When encoding the NFSACL SETACL operation, reserve just the estimated
size of the ACL rather than a fixed maximum. This eliminates needless
zero padding on the wire that the server ignores.
Fixes: ee5dc7732bd5 ('NFS: Fix "kernel BUG at fs/nfs/nfs3xdr.c:1338!"')
