Subject: [PATCH 3.12 065/116] nfs: fix inverted test for delegation in nfs4_reclaim_open_state

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

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

From: Jeff Layton <jlayton@...hat.com>

commit 1acd1c301f4faae80f4d2c7bbd9a4553b131c0e3 upstream.

commit 6686390bab6a0e0 (NFS: remove incorrect "Lock reclaim failed!"
warning.) added a test for a delegation before checking to see if any
reclaimed locks failed. The test however is backward and is only doing
that check when a delegation is held instead of when one isn't.
