Subject: [PATCH 3.11 242/272] NFS: Fix a missing initialisation when reading the SELinux label

3.11.10.1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <Trond.Myklebust@...app.com>

commit fcb63a9bd8427fc584229048ea14f1453dc9a2e1 upstream.

Ensure that _nfs4_do_get_security_label() also initialises the
SEQUENCE call correctly, by having it call into nfs4_call_sync().
