smbd: ignore set NTACL requests which contain S-1-5-88 NFS ACEs

smbd: ignore set NTACL requests which contain S-1-5-88 NFS ACEs

We apply the same "ignore" logic already in the POSIX ACL code and in the
vfs_acl_xattr|tdb VFS modules to smb_set_nt_acl_nfs4() in the nfs4_acl helper
subsystem which is common to a bunch of VFS modules: GPFS, ZFS, NFS4_xattr and
aixacl2.
