Subject: NFS: Fix size of NFSACL SETACL operations

From: Chuck Lever <chuck.lever@oracle.com>

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.
